How do I figure out what size running vest to order?

To determine your sizing for the Ultimate Direction running vests you will need access to a flexible tape measure. The process is the same as finding your waist size but your reference point to measure from is your bottom rib. If you find yourself in between sizes consider how many layers you wear while running. If you are looking for the most snug fit and do not wear many layers while running we recommend to go with the smaller size in your range.
