Omni-Freeze ICE advanced cooling technology give these shorts their clever name: the inner brief actively works to draw heat away from the body and becomes instantly cooler the second that sweat comes into contact with the fabric. Besides its heat-defeating properties, the Cool Jewel features an inner brief that fits like a boxer brief for greater mobility and comfort during activities. Outside, built in sun protection keeps UV rays at bay and special wicking technology ensures that you stay dry. Venting, gusseting and 2-way comfort stretch combine for the ultimate in comfort and fit.
