Fit Note - This top apparel is meant to fit next-to-skin. This is to enhance cooling properties and off-set the potential to chafe during endurance events . Garment will fit the tightest the first time you put it on. It will relax slightly once wet. It will never shrink or pill. If you’re not comfortable with this type of fit and or are between sizes, we recommend sizing up. CHEST - Fullest part of breast, measured as the largest part of circumference right over the pectoral muscle. WAIST - Circumference measured at the belly-button line - this is NOT the same as your pants waist size. HIPS - Circumference measured at the widest point, NOT at your hips where your belt may go. Typically this will measure just a few inches below your hip bones and around the largest part of the glutes. If you do not have a tape measure and you need something to measure with, use a belt, or smart phone power cord, and a ruler.
