This convertible backpack has wheels, should you get tired and want to drag it behind you rather than tote it around. It also has plenty of pockets for organizational and stashing purposes along with a narrow design, which is well-suited for a woman's frame. Compression straps reduce the bulk of the pack and help with balance as you make your way uphill.
