Before You Choose
Find your best fit
Every Hypelysport item is printed to order in adult sizes, so choosing the right size before checkout matters. Use the charts below to match your measurements to a size.
Made to order. Because each garment is produced upon order, please review your measurements carefully. If you are between two sizes, email [email protected] and we will help you decide before you buy.
