See our size charts here: https://www.specialized.com/size-guide

Following the size charts is the best way to get a proper fit. However, different garments are intended for different end uses and are designed accordingly. Our SL, Prime, and RBX-Series are primarily made for road riding and have closer-to-body, slim fits. Our Trail-Series garments are slightly more relaxed. There will be a fit descriptor on each product page.
