Waterproof Pack Liners

Ultralight and watertight pack liner bags for most backpacks (2 pack).

Availability: In stock

Regular Price: $5.00

Now only: $4.00



For those of you who live in the wetter climates, finally a custom-fitted liner bag to keep your sleeping bag and clothes dry. These bags, specially sized to fit your Gossamer Gear pack (though they will obviously work just as well in similar packs), are constructed of industrial-grade 2 mil virgin polyethylene film, and meet FDA and USDA specifications. They have a gusseted bottom for that custom fit. Using a bag liner for protection allows you to minimize weight by protecting only those items that you need to, and by utilizing the pack to protect the liner, permits the use of lighter materials. To close the bags, just twist and/or fold over. Arguably watertight once twisted.

The liner bags are available in one size. Some people prefer to use two bags, one for their sleeping bag and clothes they won't be getting to on the trail, and the other for clothes that they might have to pull out in rainy conditions. The bags are sold in convenient 2 packs.

  • Lightweight backpack friendly

As good as a compactor bag with a better fit!Review by Princess of Darkness
I used to always use trash compactor bags inside my backpack but they were so bulky, too tall, and difficult to find unscented. Plus you have to buy a whole box of them when I just needed one or two. This liner is much more slim so it fits better in my pack, and I love that it is see through! I can pull out the whole thing when I need to and see everything packed in there. I usually use two...one for sleeping bag, pad, and clothes and then another one for food and other items... I'm a convert. No more compactor bags for me! (Posted on 11/10/15)
