are sized like apparel. The surface area of the harness evenly distributes the weight of the pack on both the smaller and larger volumes. Measurements should be taken at widest part of chest slightly below armpits.
Custom-fit backpacks are Osprey's Legacy. Our expertise in designing backpacks that fit every shape, size and gender dates back to 1974, when Osprey was founded on designing custom packs for mountaineers headed to the Sierra.
As the leader in custom-fit backpacks, out pack-fitting technique ensures a properly fitting pack that maximise efficiency, comfort and safety both on and off the trail.

Many Osprey packs are available in multiple sizes to fit a range of torso lengths. To determine your torso measurement, please see diagram below.
