Aufbewahrungsbeutel

These Tyvek sacks are way tougher than they look for how little they weigh. Tossed my whole cook kit and a down jacket in the medium one and it shrugged off a week of being crammed in my pack. The coated material even kept my spare layers dry when my water bottle leaked all over everything else.

Wasn't sure how these would hold up but the coated Tyvek shrugs off rain and mud way better than my old nylon sacks. The medium one swallowed my puffy jacket plus spare layers, and it still squishes down flat in the pack.

Used mine on a three-week trip through the Cascades and the coated Tyvek shrugged off every bit of morning dew and trail dust without adding any noticeable weight to my pack. The assorted sizes meant I could finally ditch the jumble of plastic bags and actually see what's where at a glance.
