Liner shorts are designed to improve our comfort on long rides and fit under our favorite mountain bike shorts. The Rapha Trail Liners fit the bill and incorporate a chamois for improved comfort and reduced fatigue. The Trail Liners are made of recycled nylon and elastane for an environmentally-friendly and comfortable fit. These liners have an anti-odor treatment to keep them smelling fresh after a ride, and they are also quick-drying and moisture-wicking. Lastly, silicone leg grippers help to keep the liners in place, no matter how hard we are riding.
