Technical Information

Cycling shorts, the mountain bike rider's kilt
"It's true, cycling shorts are worn without underwear. Why? Wearing underwear risks causing irritation. Your skin can rub against the seams and elastic of your underwear. Chafing, shearing, all combined with perspiration (heat + humidity)... this is quite the recipe for infections. That is why we design our shorts with anti-bacterial pads. Dare to wear shorts without underwear!" Sylvain, Product Manager
Our care tips
Machine wash inside out on a synthetic programme at 30°C. Do not use too much detergent, and do not use softener. It is best dried on a hanger in a warm, well-ventilated place.
