Torso Sizing

Your torso size is the most important measurement and is what determines your pack size. Many Osprey packs are available in multiple sizes to fit a range of torso lengths. To determine your torso measurement at home have a friend measure the length of your back along the spine. Start at the iliac crest which is an imaginary line drawn across the top of your hip bones. From this level, measure to the C7 vertebrae, the knobby bone at the base of your neck that protrudes when you put your head down. Make sure to keep your back straight while your friend makes the measurement. If you are between sizes, it's best to find a shop where you can try on both sizes.

Interchangeable Hip Belt Sizing

Some Osprey packs, including the Xenith & Xena, Aether & Ariel and Variant series packs offer interchangeable hipbelts.To determine your hipbelt size, measure around your hips at the iliac crest (not your waist, the belt should ride on your hip bones and should fit very snugly in order to take weight off your shoulders). The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the both hip pads when securely tightened. Make sure to account for cold weather clothing for packs being used for winter activities.
