Design Philosophy The Pro SL Lite S/S Jersey is the coolest, airiest jersey Endura has ever made. Designed to help your body regulate it\'s core temperature and keep producing power even on the hottest days. Multi-Fabric Construction The front and side panels are made from a super fine, rapid wicking mesh that makes the most of the airflow over these parts of your body when cycling. The back of the jersey is made using a Translite fabric that excels in moving sweat away from your skin. Combine this with a ever so slightly shorter sleeve length and open neck and you have a jersey that will thrive on warm weather rides. 90 Day Satisfaction Guarantee So confident are we in this product that, if you are not entirely satisfied with it then we offer a no-quibble refund or replacement policy within 90 days of purchase.
