Light, simple, and built to fit seamlessly under our favorite baggies, the Castelli Trail Liner delivers impeccable comfort and breathability on the trail. A KISS AIR2 is built in so that we can go the distance without painful chafing, and the GIRO4 leg grippers keep our shorts from riding up over the course of the day.
