Trek through damp forests with confidence and dry gear. This is a good size for multiple clothing items, a tent, or a down quilt. This size fits well horizontally in most smaller backpacks.

Need a different size?  Check out the rest of our Dry Bag collection.

  • Constructed from black 1.0 oz/sqyd Dyneema® Composite Fabric which is inherently waterproof and abrasion resistant. By comparison our regular Stuff Sacks are made from thinner .55 oz/sqyd material.

  • Fully taped seams. Our dry bags will keep water out in typical backpacking conditions where the bag is not submerged.

  • The top of the bags seal with stiff velcro to make closing and rolling the top easy! Air can escape from the rolled velcro, allowing these to squish flatter in your backpack as more gear is piled on top.

  • Also check out our Zip Pouches for water and abrasion protection for your smaller items like your wallet, camera, phone, passport, glasses, etc.

  • All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.

  • Made in the USA.

Flat Dimensions: 9.75" wide x 19" tall (25 cm x 48 cm)

1.0 oz/sqyd Dyneema® Composite Fabric

Dyneema® Composite Fabric is composed of high strength Dyneema® fiber laminated inside a polyester membrane. It is inherently waterproof and does not require any coatings or DWR treatment. Dyneema® Composite Fabric has very high tensile strength for its weight and does not stretch.

1 oz/sqyd Dyneema® Composite Fabric has a thicker membrane giving it more abrasion resistance. We use it for dry bags and tent floors.

 104 lb/in (911 N/5cm)

Puncture Strength: 3.5 lb (15.5 N)

Water Resistance: 20,000 mmH₂O

Made in the USA.

Perfect Bag

I love this bag. It's the perfect size for my Thermarest Vesper 20, and fits great horizontally in the bottom of my Waymark Thru 40L pack. It's well built, and has already saved me in a heavy rainstorm in the North Cascades. I'd definitely recommend it to anyone.

Perfect For a Summer-weight Quilt

I bought this roll-top Dry Bag to keep my quilt protected from the elements. The size is great for my quilt and it stuffs easily with enough room to roll the top.

Exactly as described

Very lightweight and compact. Stows to nothing when empty and roll top allows for flexible stowing options depending on contents. All specs exactly as stated.

Medium dry bag

Bought this to put my large vesper in. Fits great! Much better than the original stuffsack. Very light weight and minimal. Fits very well with my quilt, and lightweight thermals and socks stuffed in the foot box.
