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.

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.

Medium dry bag

This is actually my second bag like this. I use one for my sleeping clothes (inside my hammock only) the other bag holds my rainsuit (top and bottom) and my puffy jacket. It's the perfect size for both.

Ordering was easy and the goods came from USA to Australia very quickly. I certainly can’t complain.

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.
