Review on Ultimate Performance Aire 2.0 Hydration Backpack for Racing and Elite Athletes - SS19 by Rene Putman

Good: - Very big and has room for everything you want to take with you for the long haul. - Nylon frayed and torn on one of the side straps - Customer service was TERRIBLE. They refused to support the poor build quality - I had to sew it myself to fix it. - Bladder room is uncomfortable and tends to fold water bladders = leaks in almost every/every bladder I've tried (x12 or so). If you must have something that will go 100+ miles unassisted and have room for clothes then this is a col pack. However, don't expect to use it for a year or more. 6 months at best once a week and the belts are dead.
