Torso Sizing
1- Find Iliac Crest - Top of hip bone.
2- On back of neck, find C7 vertebra. Touch your chin to your chest and feel the large protruding bone at the base of your neck.
3- Measure - from C7 vertebra to the iliac crest to determine torso length.
Hipbelt Sizing
To determine hipbelt size, measure around the hips at the iliac crest, not the waist. The padded portion should wrap well around the hips, leaving a gap of 3" to 6" between the tips of both hip pads when securely tightened.
