Great bags took it to northern tier. In the boundary waters bags performed above and beyond expectations.

Love these bags. I use a 10L for my seek outside cimarron and a 5L for my OR alpine bivvy, or my puffy layers (stone glacier Grumman jacket and first lite puffy pants). Have had no issues with the 10L after over a year of heavy use and abuse and the 5L has been good to me in the short time I've had it. Love all the OR products I own, and this one is no exception.

Works great, a little small for my bag.

It works well, but it is a little small for my Big Agnes Lost Dog 15* bag. It still works, but it's tight.

put clothes in bag and went to strap down and ripped the strap off barly pulling on it
