Don’t know if this is old news or not, but SEKI, Yosemite, and many others have conditionally approved The Ursack Hybrid. The Hybrid for those that do not know is the Ursack 2.0 plus the aluminum liner. Weight is 20 oz. and has a capacity of 650 cubic inches.
Well kids my pack weight just got reduced 12 oz. by this decision.
