Stop the elements from soaking your gear. The ‘Big’ size dry bag has extra space for bulky clothes or a larger sleeping bag. The girth will fit horizontally in deeper packs.

  • 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 our dry 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.

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.

Puncture Strength: 3.5 lb (15.5 N)

Water Resistance: 20,000 mmH₂O

Perfect bag

I bought a few dyneema bags from Zpacks, including this big dry bag. I put all my food in it for 5 days. I had a smaller bag for clothes. These bags are the lightest out there, and have excellent closure at the top. Highly recommended.

I use it for Bikepacking!

I love this dry bag. I needed one for my handlebar harness. It’s perfect. I can fit my duplex, tent poles, stakes, sleeping pad and pillow in it. Zpacks isn’t just for backpacking!!!
