Measuring Your Torso To Determine Your Pack Size
Take a couple of minutes to accurately measure sizing will yield the best fitting pack possible. Follow these 3 easy steps:
1. Find the Iliac crest (the top of the hip bone)
2. Find the C7 Vertebra (the largest bump at the base of your neck)
3. Measure from the C7 down along the spine to where it intersects with the Iliac Crest. Use the table below to then determine your correct pack size.
