– Wayne S., ★★★★★

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 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.
  • 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.
