Torso Sizing

Our Backpack from Osprey offers adjustability to fit a range of people with different heights and proportions; this way, your Osprey Backpack can still fit through a growth spurt or two. So how do you know what's right for your height and proportion? First, you'll want to know your torso length. To determine your measurement, see the diagram below.

This measurement starts at the iliac crest, which is the top of your hipbone on the side of your body that acts like a shelf. From this point, measure to the C7 vertebra, the knobby bone at the base of your neck when you put your head down.
