Clear Waterproof Pack Liners

A pack liner does one job: keep your gear dry when everything outside is soaked. These clear bags from Gossamer Gear seal out water without adding noticeable weight to your load, and the transparent material means you can see what you packed without tearing everything apart at camp.

You get two liners in each pack, both redesigned with added height to handle more volume. Roll the top a few times, fold it over, and your sleeping bag, spare clothes, and anything else that cannot get wet stays bone-dry through downpours, stream crossings, or an unexpected topple into a puddle.

The clear construction is more practical than it first appears. Instead of rooting through an opaque sack in dim light or dumping everything onto wet ground, you identify what you need at a glance. That matters most when you are tired, cold, and trying to set up shelter in foul weather.

Gossamer Gear built these for backpackers who track every gram but refuse to gamble with soggy gear. The material is light enough that carrying two liners weighs less than a single heavy-duty dry bag, yet still forms a reliable seal. Use one for sleep system and insulation, the other for clothing or electronics.

These liners fit inside most backpacks without fighting for space. They conform to the shape of your pack rather than forcing your gear into a rigid cylinder, so you retain access to every corner of your main compartment. When you are not using one, it rolls into a bundle smaller than a deck of cards.
