The Big Stuff Sack is large enough to hold my overnight camping clothes down to freezing temperatures and fits perfectly sideways in my Arc Haul Zip. While it doesn’t have a dry bag closure, I think it would provide protection from bladder or other leaks inside the pack.

– Doug L., ★★★★★

This big sack will fit multiple clothing items, larger tents, bigger sleeping bags, or other soft bulky items. This stuff sack is spacious but still lightweight thanks to the Dyneema® Composite Fabric construction. It will fit well horizontally in larger backpacks.

Abigail ★★★★★

Took this sack on a freezing overnight trip and was surprised how much I could shove in—it held every layer I brought down to about 20 degrees. The lack of a dry bag closure doesn't bother me since I just pack my rain shell on top.

John C. ★★★★★

Slid into the sideways pocket of my Arc Haul Zip without a fight, and somehow all my below-freezing layers fit without turning into a giant lump. I was prepared to wrestle with a dry bag twist, but the lack of one honestly made packing faster—just stuff and go.

Edward ★★★★★

I was dreading the squeeze, but the sack swallows my whole cold-weather kit, and the way it tucks sideways into my pack is almost too easy. The lack of a dry bag closure is fine for a car-to-camp hop, and the fabric feels tough enough to drag over rocks.
