High quality in construction. Extremely light weight and super durable.

– 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.

DCF Pack liner

Works as expected. Nice full velcro closure with locating tabs in the middle of each side for quick alignment. Roll it down a couple times and secure it with the plastic buckle. Easy to use. It says that it's black but it's translucent which makes it easier to see inside. Would suggest it to friends.
