SIZING TIPS
[Step 1] Put on a typical shirt that you plan to wear beneath your vest
[Step 2] Relax your arms to the side and have someone use a 'clothing measuring tape' to measure the fullest part of your chest. Larger riders need to measure the fullest part of their stomach also.
If you do not have a clothing tape, then use a string; mark & measure the string with a carpenters tape when finished
[Step 3] This is YOUR CHEST measurement. Each sizing chart has a section that is labelled, "YOUR CHEST".
