Made to wear under your baggies, the Castelli Trail Liner prioritises comfort and breathability. It is made from light, airy mesh, with flatlock stitching ensuring a smooth finish, and is built around the soft KISS Air² seat pad.There’s no fear it will shift and allow the seat pad to move out of place as you ride, since the waist is secured with elastic, while the leg endings are held firm by GIRO4 grippers, with the silicone arranged in vertical lines to offer compression without pressure.Features:Comfortable and breathable mesh undershortsConstructed with smooth, flat lock stitchingKISS Air² seat pad delivers long-distance comfortWith elastic waist and GIRO4 leg grippers with raw edges
