I'm not sure if I need short or regular length. How do I choose?
The lengths listed above are for the actual strap. There are a couple of factors in determining which strap length will work best for you, which are the width of the pack you'll be using it with, and whether or not you intend to wear it crossbody or around your waist. For an average body type, the short strap works best as a waist belt or short crossbody, and the regular strap works best for standard crossbody.
