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. Multiple sizes are available.

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

  • The top of the pack liner seals with stiff velcro to make closing and rolling the top easy! Air can escape from the rolled velcro, allowing these to squish down in your backpack.

  • 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.


Tensile Strength:
 104 lb/in (911 N/5cm)

Puncture Strength: 3.5 lb (15.5 N)

Water Resistance: 20,000 mmH₂O
