It’s tough and does everything you’d want. What more is there to say? Kept my stuff dry in record breaking rains in Arkansas on Eagle Rock Loop.

Supersize your dry bag and protect your biggest pieces of gear from the elements. This size will fit a larger sleeping bag, a bunch of clothes, or any other soft bulky item. The rectangular shape fits well in all of our backpacks, either standing vertically or sideways depending on the pack volume. The wide opening makes it easier to dig through the bag and find what you need.

  • 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 bags have a stiffened opening to make rolling the top down easy and secure.

  • Squeeze out the air and roll down the top to compress your gear as needed.

  • 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.
