Breathability, temperature control, and moisture management are key to keeping you comfortable on the bike. The Trail Liner is designed to provide these. Made from a super-breathable mesh material throughout, which provides for maximum breathability and airflow to keep you cool and dry throughout your ride. For comfort at the leg ending we use our GIRO⁴ leg gripper with raw edges. The silicone runs in vertical stripes to avoid the sausage effect. And, of course, you need a great seat pad to enjoy your ride. The KISS Air² seat pad provides all-day comfort for your next gravel, mountain bike, or adventure ride.
