The first iteration of the Kletter Flip debuted in 1975, and the minimal pack's unique zippered flip-up lid, side straps, and roomy interior have been winning over wearers ever since. Skip this one if you need lots of pockets to keep organized; choose it if you want a simple, hard-wearing pack. [$197;]
