The best waterproof patio cushion storage bag for winter is a zippered, extra-large bag with handles that matches your cushions’ real dimensions, and among the eight listings below the 68-inch models (68 x 30 x 20 inches in their titles) give the most flexibility for a typical patio set. The two-pack versions are the most economical way to store a larger set, and the single bags are better when you only need to protect a few seat cushions. Whichever you choose, the bag is only half the job: cushions that go in damp will come out mildewed, no matter what the fabric is rated for.
This guide is written by the Editorial team using published specifications, manufacturer documentation and buyer reviews. It covers each listing based on what its title actually says, shows you how to calculate how many cushions fit in a bag, and walks through a drying routine that protects what you store. Where we use a number beyond the title, it is labeled as an estimate with its assumptions stated.

The eight bags, one by one
Uthem 177 Gallon Outdoor Cushion Storage Bag (68 x 30 x 20 inches, 1 pack)
This title is the most complete of the single-bag listings: it names the capacity as 177 gallons, the dimensions as 68 inches long, 30 wide and 20 high, and states waterproof construction, a zipper, handles and black color. The 177-gallon figure checks out against the dimensions: 68 x 30 x 20 is 40,800 cubic inches, and dividing by 231 cubic inches per US gallon gives about 177. That is a nominal, fully expanded volume, not what a squishy cushion stack will actually occupy.
In practice, a bag this size suits a bench cushion plus several seat pads, or a loveseat set with its back cushions. The 30-inch width is useful because most square seat cushions (commonly 20 to 24 inches) can lie flat without being bent, which is kinder to foam. The 20-inch height lets you stack a handful of 3- to 4-inch cushions before the zipper begins to strain. We cannot say how thick the fabric is, how the seams are finished or whether the zipper has a protective flap, so those are details to confirm on the listing and in the buyer questions.
Because the title says waterproof rather than water-resistant, it matches the wording of the keyword, but the term is not a certified rating. Treat it as a good sign, not a promise that the bag will survive standing water or pooled snowmelt. Place the bag on a pallet, shelf or plastic crate rather than on bare concrete.
Pros
- Title states both capacity and exact dimensions, so you can plan the fit
- 30-inch width suits flat storage of typical seat cushions
- Zipper and handles are both stated in the title
- Single bag keeps the purchase simple if you need only one
Cons
- Fabric weight, seam finish and zipper type are not in the title, so check the listing
- Single pack means a bigger set needs a second purchase
- Waterproof wording is a seller claim, not a standard rating
Who it’s for: households with one bench or a small conversation set who want one large bag and prefer a clearly stated size.
Could Spark 68-inch Extra Large Waterproof Storage Bag (heavy duty, zipper and handles)
The title advertises a 68-inch bag described as extra large and heavy duty, with a zipper and handles, and it lists multiple uses: chair cushions, Christmas tree storage, pool decor and moving. The color is shown as black, with black or beige mentioned in the title. What the title does not say is the width and height, so you cannot calculate the fit from this listing alone. If the 68-inch length matches the 68 x 30 x 20 sizing shown by other bags in this guide, the interior would be similar, but that is an assumption, so confirm the full dimensions before you order.
This is the lowest-priced single bag in the set, which makes it the sensible starting point for a small patio. The multi-use wording suggests the seller expects it to be used for bulky soft items beyond cushions. That versatility is useful if you also want a place for off-season pool floats or an artificial tree, but it also signals that the bag may be sized more for general storage than for patio furniture specifically.
An estimate for planning: if the interior is close to 68 x 30 x 20 inches, you could store roughly five or six chair sets (a seat and back pad) if you avoid overstuffing. If the width is narrower, plan for fewer. Heavy duty is another seller phrase that needs a closer look at the listing for a fabric weight or denier figure.
Because it is a lower-cost bag, it makes sense to inspect the zipper pull, stitching along the handle bases and any edge binding when it arrives, while the return window is open.
Pros
- Lowest-cost single bag in the group
- Title names 68-inch length, zipper and handles
- Multi-use wording covers tree, pool decor and moving
Cons
- Width and height are not in the title
- Heavy duty is not backed by a stated fabric figure in the title
- Bag is generic in purpose, so fit for your cushions needs checking
Who it’s for: budget-minded owners of a small set who will confirm the dimensions before buying.
Bicherub Patio Cushion Storage Bag, 2 Pack (68 x 30 x 20 inches, waterproof)
This listing describes a waterproof, extra-large, protective zippered bag with handles, 68 inches long by 30 wide by 20 high, sold as a two-pack. It is the highest-priced listing here, but each bag costs about half the listing price, so the real comparison is against buying two single bags. For a four-chair dining set with seats and backs, two bags let you separate seat pads from back cushions, label each, and carry them without bending.
The title does not mention reinforced handles, double zippers or a specific fabric. Check the listing for those. It also appears next to a one-pack Bicherub listing in this group, and the two titles use different wording: this one says waterproof, while the single says water-resistant. That may be a copy difference rather than a material difference, so compare the full descriptions and the questions on each page before assuming either is better.
A planning estimate: assuming 24 x 24 x 4 inch seat cushions (2,304 cubic inches each) and a sixty percent usable fill, two bags hold about 12 such cushions together, comfortably covering a six-seat set with a few spare pads. Those figures are estimates for planning, not measurements of the product.
Because you receive two, it is worth deciding in advance which bag holds what, for instance one for seats and one for backs and accessories, so you are not hunting through both in spring.
Pros
- Two bags in one purchase, so the per-bag cost is lower than the listing price suggests
- Same 68 x 30 x 20 inch size as the other large bags
- Title states waterproof, zipper and handles
Cons
- Highest listing price in the group, which only pays off if you need two bags
- Wording differs from the single-pack Bicherub, so check which is which
- No fabric or zipper specifics in the title
Who it’s for: owners of larger sets who want matching bags to divide seat cushions from back cushions.
Bicherub Water-Resistant Extra Large Storage Bag (68 x 30 x 20 inches, 1 pack)
The one-pack Bicherub listing shares its dimensions with the two-pack but is worded water-resistant rather than waterproof. The title says protective, zippered, with handles, and gives the 68 in L x 30 in W x 20 in H size. That makes it a safe choice if you have a small set, or if you want to try one bag before committing to more.
The wording difference matters for expectations. Water-resistant usually suggests that the fabric sheds rain and splashes, while waterproof implies a tighter barrier, but neither term is a standard rating. If the bag will sit in a covered garage or shed all winter, the difference is minor. If it will sit outdoors under a tarp, it is a bigger deal, and you should read the product description for seam and zipper detail or consider placing the bag inside a covered deck box, such as the ones in our guide to waterproof deck boxes for cushion protection.
For fit, the volume math is the same as the other large bags: 40,800 cubic inches nominal, about 177 gallons, and a sensible planning fill of around sixty percent, or roughly 24,500 cubic inches. That is about six chair sets of the 24-inch size described earlier. Treat that as an estimate.
It is the sensible partner if you already own a Bicherub bag or want a matching second one later, because both appear to share their dimensions.
Pros
- Same large dimensions as the two-pack, in a smaller purchase
- Zipper and handles stated in the title
- Clear size makes the fit easy to calculate
Cons
- Water-resistant wording is weaker than the waterproof wording elsewhere
- Two single bags may cost more than a two-pack
- No fabric details in the title
Who it’s for: small-set owners storing indoors who want a straightforward large bag.
AIGOTSUKI 2 Pack 177 Gallon XXL Waterproof Storage Bag (dual zippers, reinforced handles)
This title packs in the most features of the group: a two-pack, 177 gallons, waterproof, 68 x 30 x 20 inches, reinforced handles and dual zippers, described as a tote-style bag in black. Dual zippers matter because a single long zipper can be awkward on a bag this size. With two sliders you can open from either end, or open the center and reach in without unzipping the whole thing.
For winter storage, easier access means you will be more likely to open the bag once mid-season, check for dampness and let it breathe, which is good practice. Reinforced handles are also a practical point since a full bag with several cushions can feel awkward to lift. We cannot confirm the weight rating of the handles, so we advise carrying a full bag with two hands or sliding it rather than lifting by a single handle.
As with the other two-pack, the listing price is higher but the per-bag cost is about half. If you only need a single large bag, the extra feature set may not justify buying the pair. If you have a dining set with two benches, the matching pair will keep the cushions grouped by furniture piece.
Compare this one against the Bicherub two-pack: both name the same size, and this one adds the dual-zipper and reinforced-handle detail. Both are positioned as premium by listing price, so your decision may come down to the closure you prefer.
Pros
- Dual zippers stated in the title for easier access
- Reinforced handles mentioned
- Two bags in the pack, with the same size as the other large models
Cons
- Premium listing price for the pack
- Fabric and seam details are not in the title
- Waterproof wording is a seller claim
Who it’s for: owners of bigger sets who value easy access and are happy to buy two matching bags.
AEGIS COMFORT CARE Outdoor Cushion Storage Bag (48 x 16 x 22 inches)
This one is clearly narrower than the 68-inch bags: 48 inches long, 16 wide and 22 high, with a handle and zipper, and described as waterproof. The volume works out to 16,896 cubic inches, or about 73 gallons. That is less than half the capacity of the 68-inch bags, and the 16-inch width is the key limit.
A 24-inch square seat cushion will not lie flat in a 16-inch-wide bag, and at 22 inches high it will not stand on edge either without folding or compressing. This bag is better suited to smaller or narrower items, such as bench pads, long lounge cushions that can be rolled or folded, or items like folded blankets and pool accessories. If your cushions are around 18 inches square, it may work. Measure first.
Narrow bags do have one advantage: they take less floor space in a small shed and can slide onto a shelf more easily. If you have a balcony set with a couple of small pads, this size can be a fit, and the lower listing price makes sense for the reduced capacity.
A planning estimate with stated assumptions: with an 18 x 18 x 3 inch cushion (972 cubic inches) and a sixty percent fill, about ten such cushions would go in by volume, though the geometry of rolling may reduce that.
Pros
- Compact footprint for small storage spaces
- Title lists exact dimensions and waterproof wording
- Lower listing price than the 68-inch bags
Cons
- 16-inch width excludes standard 24-inch square cushions laid flat
- Less than half the volume of the big bags
- No fabric details in the title
Who it’s for: balcony and small-patio owners with compact cushions, or anyone who needs a secondary bag for narrow items.
NettyPro Outdoor Patio Cushion Storage Bag (50 x 15 x 25 inches, brown, water-resistant)
The NettyPro title states water-resistant (not waterproof), a zipper and handle, and a size of 50 x 15 x 25 inches in brown. It also mentions Christmas tree storage for a 7.5-foot tree. That tells you the shape: a tall, narrow bag, with a volume of 18,750 cubic inches, about 81 gallons.
The 15-inch width is the limiting dimension for cushions, much like the AEGIS bag. A tall, narrow bag is excellent for a disassembled artificial tree, folded camping chairs or rolled items, but it is a poor shape for flat patio seat pads. If your cushions are small or you plan to roll long bench cushions, it may work, but check carefully. It is a case where the keyword and the shape do not perfectly align, so we call it out plainly: it is better thought of as a general soft-goods storage bag that can also hold some cushions.
Water-resistant wording and a brown color may appeal if the bag will remain visible in a garage or on a covered porch. If you need maximum weather protection, though, the waterproof-labeled bags are closer to the keyword.
An estimate: if you store 18 x 18 x 3 inch cushions on edge, fifteen inches of width allows only 15 inches of the cushion to fit across, so they would have to be compressed. As a planning assumption, treat this bag as a rolled-cushion or tree bag and not a flat-stack bag.
Pros
- Tall shape suits rolled or upright items, including an artificial tree
- Brand and color are named in the title
- Mid-range listing price for the group
Cons
- Water-resistant rather than waterproof
- 15-inch width limits standard cushions
- Less natural fit for flat seat pads
Who it’s for: households with a tree, folding chairs or rolled bench pads to store, plus a few small cushions.
GARPROVM Extra Large Patio Cushion Storage Bag (68 x 20 x 30 inches, 420D Oxford fabric)
The GARPROVM title lists the size as 68 x 20 x 30 inches with carry handles and 420D Oxford fabric. The numbers are the same as the other big bags but the order differs: 30 inches is placed last, so the bag may be listed as 20 inches wide and 30 inches tall. That ordering changes how you pack it: a bag that is 30 inches high stands differently from one that is 30 inches wide. Check the listing images to see how the bag lies when full.
The 420D Oxford fabric mention is the most specific material clue in this entire group. The D stands for denier, a measure of yarn thickness, and a higher number generally suggests a heavier yarn, though denier alone does not describe coatings, seam taping or waterproofing. Treat it as a useful detail, not a waterproof rating. The title says waterproof, which is the seller’s claim.
It sits at the lower end of the price range, which makes it a value option among the big bags, especially for people who want a stated fabric and do not need a two-pack.
A planning estimate: if the interior is 68 x 20 x 30 and you store 24-inch cushions, you may need to stand them on edge along the long side, which works because 30 is greater than 24. If it is the other way around, they will lie flat in the 20-inch width only when folded. Confirm using the listing photos.
Pros
- Fabric named in the title (420D Oxford)
- Large 68-inch length with carry handles
- Lower listing price among the big bags
Cons
- Dimension order may be confusing, so check how it stands
- Zipper details are not in the title
- Denier is not a waterproof rating
Who it’s for: value-minded shoppers who want a stated fabric in a large single bag.
How we picked these
Nobody on the team used or measured these units. The Editorial team compared the eight listings using published specifications, manufacturer documentation and buyer reviews, and we kept each description to what the title says. Any detail not in the title, including seam type, zipper style, coating, stated load limit or color options, is something to check on the listing. We did not copy ratings or review counts, and we do not give exact prices because they change.
We looked at five things. First, size: the title dimensions and any capacity figure. Second, the closure: zipper, single or dual, and handles. Third, the weather wording: waterproof versus water-resistant. Fourth, the pack count, since two-packs change the per-bag cost. Fifth, the shape, because a 16-inch-wide bag and a 30-inch-wide bag are different tools. Several listings are near-duplicates of one another in size, so the differences come down to wording, pack size and price tier.
Worked example: how many cushions fit in one bag?
Here is a simple calculation you can repeat with your own numbers. Assumptions: a typical seat cushion of 24 x 24 x 4 inches, and a back cushion of 24 x 18 x 4 inches. The seat is 2,304 cubic inches and the back is 1,728, so one chair set is 4,032 cubic inches.
A 68 x 30 x 20 bag has a nominal 40,800 cubic inches. A soft bag never fills perfectly because of zipper clearance, rounded corners and compressed foam, so we use a planning fill of sixty percent, which gives about 24,480 cubic inches. Dividing by 4,032 gives about six chair sets. That is an estimate, and the actual number depends on foam density and how much you compress it.
Now compare the geometry. The bag is 30 inches wide, so a 24-inch seat lies flat. Stack height is 20 inches, which allows about five 4-inch cushions in a stack. Two stacks fit lengthwise, since 68 divided by 24 is a little over two. So you could fit around ten flat seat pads, and then put the back pads in the gaps or a second bag.
For the 48 x 16 x 22 bag, a 24-inch cushion does not fit flat in either 16 or 22 inches. Use the rule: the cushion’s two largest dimensions must be able to pass through the bag’s two largest openings after compression. Write your cushion sizes down before you shop.
Keep stored cushions dry: a pre-bagging routine
Waterproof bags protect against outside water, but they also trap whatever is inside. Use this checklist before sealing:
- Choose a dry day and let cushions sit in the shade for a day or two so the foam core is dry, not just the surface.
- Brush off leaves, dirt and bird droppings. Spot-clean following the care label, then dry fully.
- Remove removable covers if the label allows and wash them per the label instructions.
- Put a breathable layer, such as a cotton sheet, around the stack so fabric does not touch the bag walls.
- Add desiccant packs or a moisture absorber designed for closets, following its instructions, and keep it away from children and pets.
- Leave the zipper slightly open for the first night if you are unsure, then close it.
- Open the bag once mid-winter on a dry day to check for odor or dampness.
If you find mildew, do not seal the cushions again. Follow the cushion maker’s cleaning guidance, and use gloves and a mask if there is visible mold growth. For anything more than a light surface issue, consult the manufacturer’s care instructions or a professional cleaner.
Where the bag sits matters more than the bag
A bag on a concrete floor sits on a cold surface that can sweat in winter. Use a pallet, a shelf, a plastic crate or even a few boards. Avoid placing it right against an exterior wall, where it may touch condensation, and avoid putting heavy objects on top that could crush foam or stress seams. In a shed, keep bags away from lawn chemicals, fuel and fertilizer. Do not store flammable items inside fabric bags.
If the only available space is outdoors, a bag is not a substitute for a lidded box. In that case, consider a deck box or a heavier cover as covered in our guide to patio furniture covers for winter storage and protection, and use the bag inside it for an extra layer.
Mistakes that ruin stored cushions
- Bagging damp cushions. Even a tiny amount of moisture can bloom into odor after weeks. Dry first.
- Buying by capacity alone. A 177-gallon figure means little if the width is smaller than your cushion.
- Overstuffing. A bag you have to force closed puts stress on the zipper and seams.
- Ignoring the floor. A bag on bare concrete can pick up moisture from beneath.
- Assuming waterproof means breathable. It does not. Plan for airflow before and during storage.
- Skipping the mid-winter check. One quick opening in dry weather catches problems early.
Verdict: which bag to pick
For most patios, a 68 x 30 x 20 inch bag is the safest size. If you want the simplest single purchase with a clearly stated size, the Uthem 177 Gallon listing is a good middle choice. If you need to spend less and are willing to confirm dimensions first, the Could Spark and GARPROVM listings are the budget routes, with GARPROVM adding a stated 420D Oxford fabric. For larger sets, a two-pack from Bicherub or AIGOTSUKI makes sense, with the latter adding dual zippers and reinforced handles. Choose the AEGIS or NettyPro only if your items are narrow, or if you need a bag for a tree or small cushions. Whatever you pick, keep the cushions dry and the bag off the floor, and spend a few minutes on the checklist before you zip up for winter.

Frequently asked questions
Are waterproof cushion storage bags enough to stop mildew over winter?
No. A waterproof shell keeps rain and snowmelt out, but it also holds in any moisture already inside the cushions. Mildew usually comes from damp foam or fabric being sealed up, not from the bag leaking. Let cushions dry completely for a day or two in dry weather, brush off debris, and consider desiccant packs or a cloth wrapper. If a cushion smells musty when you open the bag in March, it went in damp.
How do I know whether my cushions will fit a 68-inch bag?
Measure each cushion length, width and thickness, then check the two largest dimensions against the bag’s length and width after the cushion is slightly compressed. Titles list the outer measurements, but a soft bag never fills to its full volume. As a rough planning estimate, count on using about sixty percent of the nominal volume. If your cushions are 24 inches square, a 30-inch-wide bag takes them flat, while a 16-inch-wide bag does not.
Should I store the bag in the garage, shed or leave it on the patio?
A dry, covered, off-the-floor spot is best, such as a garage shelf, a shed with a raised pallet, or a basement. A bag left on bare patio stone collects condensation underneath, and snow load or freeze-thaw cycles can stress seams and zippers. Pests also like quiet fabric stacks, so keep food, pet bedding and open bird seed away from the stored bags and check them once mid-winter.
Is water-resistant the same as waterproof for a storage bag?
Not necessarily. Seller wording varies, and neither term is a standard rating on its own. Look at the fabric description, how seams are finished and whether the zipper has any cover or flap. Because a listing may say water-resistant while another says waterproof for a bag of the same size, read the full description and buyer questions before assuming a difference in protection.
Can the same bag hold something other than cushions?
Several of these listings mention uses such as artificial Christmas tree storage, pool decor or moving. That works for soft or bulky items, but avoid sharp, heavy or damp items, and avoid loading to the point where the zipper strains. Check the listing for any stated load limit, and keep chemicals, fuel or anything flammable out of fabric storage bags entirely.
