Osprey Sizing Chart

Pack Frame Size
Your correct frame size is found by measuring your torso from the seventh vertebra (the big bump where the shoulder slope meets the neck) down the spine to the point in the small of your back which is horizontally level with the top of your hip bones (iliac crest). To find the iliac crest, use your fingers to trace the hip bone upwards until you can feel the point where the top edge of your hip bones curve inwards, on the side of your hip, creating something of a shelf. Holding your finger on the seventh vertebra, measure down your back to the point in the small of your back level with your iliac crest (see figure at left). The measurement is most easily obtained using a string or a cloth tape and help from a friend. This is your torso length, and using it, you can now select the correct frame size.
