Size Guide

Use the guide below to select the perfect size for any ASSOS item. But don’t worry, if you don’t get it exactly right, we offer free returns. Note ASSOS apparel is carefully designed and constructed to fit best in the riding position. It’s normal for our apparel to be a bit constricting when standing fully upright—but when you move into the riding position, you’ll feel the garment “click” into place and seemingly disappear. If you’d like further sizing assistance prior to purchase, please get in touch with us here — we’ll be happy to help.
