Sometimes you are done in a day. Sometimes you extend the adventure. Either way, the Aerios 30 goes with you. Sized right for ultralight overnights, but not too big for extended day trips, it is exceptionally versatile. The breathable AeroForm back panel, padded hipbelt and highly adjustable harness combine for a comfortable carry. Multiple external pockets are secure and accessible, and the lightweight fabric has a liquid crystal polymer ripstop grid for outstanding durability.
