Please note that the info provided above refers to the torso size the pack will fit, and NOT any dimensions of the pack. Below are steps for how to get your torso length. You should have someone help take this measurement for you so it is accurate.
HOW to MEASURE TORSO LENGTH:
1. Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt.
2. Touch your chin to your chest to find the C7 vertebrae, the knobby bone at the base of your neck.
3. Make sure you keep your back as straight as possible while measuring.
4. Measure the full length from the C7 vertebrae to the iliac crest. This torso measurement determines what size Osprey pack you should carry. Refer to the size chart above to find your ideal size.
5. If you are in between sizes, it is ideal to try them both on before ordering.
