What Our Gearhead(R) Experts Are Saying: "I wear this liner under baggies for everything from quick laps to long trail days. The pad is supportive without feeling bulky, and the fabric stays comfortable even when the ride turns hot and sweaty."When we're riding trails for hours at a time, comfort underneath our outer shorts can make or break the day. The Trail Bike Liner Short is built to quietly handle sweat, friction, and saddle pressure so we can focus fully on the ride ahead instead of mid-ride adjustments. Breathable four-way stretch mesh moves naturally with every pedal stroke, while flatlock seams keep chafing at bay during long climbs and fast descents. BN3TH's Original 3D Pouch creates friction-free support and better airflow where it matters most, and a low-profile cycling pad adds targeted cushioning without bulk. The result is a liner that stays comfortable, supportive, and easy to forget you're wearing.
