Our 30-Day Trial program is designed to help you choose the right training shorts for you and your lifestyle. You can try each style once before paying to see what's best for you and how you workout - we’re confident they won’t disappoint. If you love them - keep them! If you don’t, just send them back within 30 days of your purchase date - you won’t be charged and return shipping is on us too. All we ask is that you tell us why they didn’t work for you.
