Used these so far on a couple trips and strongly prefer them over Opsacs. Much lighter, stronger and easier to close (fold over, like a roll top bag). Very affordable. Arrived much quicker than anticipated.

I thought they were fine except I had expected them to seal since they are supposed to keep bears from smelling my food. Delivery was fast though and the cost was less than lots of other ones

Anything to try to keep the animals at bay. I use the large one for more waterproofing in my pack. The small one to keep in my food bag. I’ve had raccoon, bob cat, and big Georgia coyote that looked like wolves to me, in my campsite. Live and learn now I always odor proof and hang my bear bag now. These bags are ultralight and odor proof. I like them. I love Zpacks gear, anyways.

This works great to stuff my quilt, puffy, and clothes in the bottom of my pack. Saves room, no messing with multiple “dry” bags. Thanks ZPacks!

I purchased a Duplex, and an ArcZip bag, along with a few goodies. I’m heading out to do the Long Trail in Vermont, 273 miles, tomorrow morning!! So, starting then, the gear will get the test. Remind me, and I’ll definitely give you real world beta in the items. Love the fit and workmanship, plus the extras I ordered were already attached! Sweet!!
