I am buying a pack for my son, he is 6' 4" would this pack fit?
SunnySports S Sizing for a backpack is to his torso length, not his height. Don?t assume he needs the tall model just because of his height. To find his torso length, have someone measure from the iliac crest at the top of his hipbone to the prominent bone at the base of his neck (the seventh cervical vertebrae). Once you know his torso length find a pack that his torso length fits in to its "torso fit range". Stay safe and have fun out there! Neal
