    Comments about Black Diamond Infinity 50 Backpack:

    I used this pack on a two day backpacking trip in the smokies and it was Amazing! The hipbelt moves unlike any other pack I've tried because of the swivel hipbelt. The water bottle pocket is easy to get to when the pack is on and I like the simplicity of the big mesh pocket on the outside of the pack. Be sure you get someone to adjust the pack to fit your torso. The allen wrench to adjust the pack is in the hipbelt pocket. The only thing I wish this pack had was two hip pockets instead of one.
