Whether we're ripping a new gravel trail or gearing up for a training ride on the road, the Assos UMA GT Summer Half Tights C2 deliver extra protection and comfort to keep us pushing through. Its Type. 429 fabric, built with nylon and elastane, fits firmly against our legs for a slightly compressive fit, while the pre-shaped paneling ensures optimal freedom of movement during each pedal stroke. For seated comfort during a ride of any length, Assos uses their shock-absorbing UMA GT C2 insert that is kept in place by the hipClick waist construction.
