The ergonomic fit supports your body while in motion, to help you perform better every time you pull them on. Optimal fabric choice gives you the perfect amount of stretch, with a little bit of extra give in key areas like the waist, knee and ankle. The innovative Powerband compression cuff reduces pressure on your lower leg – without restricting circulation – while flatlock seams are designed to eliminate chafing and skin irritation. A single back pocket provides storage space for a phone, MP3 player or gels, while reflective accents on the back, front and bottom of the Knickers add some extra night-time visibility. The AirSport chamois is engineered to reduce chafing and pinching, delivering a smooth transition from one position to another.
