Description
A waterproof backpack liner built to replace trash compactor bags and Nylofume for good. Where plastic rips and leaks in weeks, this liner lasts for years. For the same trip count you'd burn through 10+ trash bags, one Ultralight Pack Liner keeps going. Offering both environmental and economical sustainability to your outdoor expeditions.
Made from waterproof, ultralight Challenge D50T fabric, (a trusted material in many dry bags and food bags), with fully sealed seams and a durable outer abrasion layer to protect against tent poles, stakes, and rough gear rubbing through your pack. No leaks, no trailside duct tape patch-ups. It's also lighter than a Dyneema pack liner, at a fraction of the cost, and trusted by thru-hikers on the Appalachian Trail (AT), Pacific Crest Trail (PCT), Continental Divide Trail (CDT), and beyond. Backed by a 5-year warranty and handcrafted, made to order in the USA.
Picking the Right Size for Your Backpack
Lay your backpack flat and measure the width. Your pack liner should be just slightly wider than your pack, height doesn't matter much since your tent and other non-critical items sit below the liner anyway.
