Osprey Men's Pack Size Guide
Sizing Overview
Fit should not be compromised for any other considerations. Body shape and sizing varies from customer to customer. Not every customer will fit every pack. Adjustable packs allow customers to fine-tune the fit for optimal carry performance.
Torso Length/Sizing
Many Osprey packs are available in multiple sizes to fit a range of torso lengths. To determine your torso measurement, follow these simple steps to determine your size.
1. Find iliac crest (Top of hip bone)
2. On the back of the neck find C7 vertebra - Touch your chin to your chest and feel for the large protruding bone at the base of your neck
3. Measure from C7 vertebra to the iliac crest to determine your torso length
