Like it so far!
Only had this pack for a few weeks. Used it on a 20+ mile backpacking trip in Moab, UT. Worked great. One complaint, however, is the small stretchy pocket on the outside has a pin hole in it from where it snagged on a boulder. The material is not the type of material that would withstand sharp or tear situations. Only other complaint is the pack does not come with a drinking hose magnet for the chest strap like the smaller water bladders do...nor does the pack come with a water bladder and hose. You can purchase these in a package for additional $$, but I would have liked to see them come with the pack for as much money as I paid for it. Overall I am very pleased with the pack so far however. I would recommend it to a friend. I own an Osprey day pack / water bladder (3L) and love it as well.
