Pack Liner Dry Bag

$45.00 Weight 1.8 oz / 51.0 g
Lead Time 1 Week

This full size roll top dry bag protects the entire internal contents of your backpack. This is a good option if you prefer to use non-waterproof stuff sacks instead of individual dry bags. It is also nice as an extra layer in very wet environments. It is sized to fill out the main compartment of any of our backpack sizes, and will fit most similar volume backpacks.

This is also available in a heavier material with a handle for dual-use as a protective Airplane Case for checking your backpack on an airplane.

  • 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 .51 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.
