Castelli Trail Liner Description:

Breathability, temperature control, and moisture management are key to keeping comfortable on the bike. The Castelli Trail Liner is made from a super-breathable mesh material, providing maximum breathability and airflow for increased comfort. The GIRO4 leg grippers keep the liners from riding up while the raw edges make for a seamless transition to the skin. The final and most important feature is the seat pad, the KISS AIR2 seat pad provides all-day comfort for gravel griding, mountain biking, or adventure rides. Add this liner under a favorite short and hit the trails.

Castelli Sizing: Many Castelli products are designed with a European race-fit. It is not uncommon to size up one or two sizes for the right fit.

Note: All measurements are provided by the manufacturer and may vary depending on how measurements are acquired. Castelli instructs that for best results measurements be taken over underwear. Castelli recommends sizing up if measurements fall between sizes for a better fit.
