[This review was collected as part of a promotion.] This product is great for hiking and biking! I often like to bike and then hit the trails and this is a great pack for both.
Pros: Easy To Access Items, Easy To Carry, Easy To Identify, Good Capacity, High Quality, Lightweight, Stylish
Pros: The pack is good - small and light. Chest and waist straps keep it from bouncing around (I use it while biking). Cons: Bite valve leaks badly. My older High Sierra's valve lasted several years before going bad. Seems the quality went down.
