We love Pearl Izumi for their practical accessories that won't break the bank. The Transfer Lite Skull Cap is a nice addition to your kit to help you stay cool and dry, especially if temperatures start to rise. The P. R. O. Transfer material absorbs sweat and transfers it to the outside of the fabric to speed up evaporation. This lightweight fabric shelters your skin from UV rays while remaining breathable enough to keep you cool on taxing climbs. The material is stitched together into anatomic panels that fit flush against your head for a comfortable fit under your helmet. An elastic band holds the cap securely in place and fits almost any head size.
