400-mile pad is a float pad, dries quickly and has become very popular for all types of triathlons. This pad floats and stretches which means it can be used as a race piece in a triathlon. On the bike, the pad stretches with the short and follows your skin as it moves with every pedal stroke, eliminating the friction that can cause irritation or rashes. Forza & Liftfoil™ fabrics complete a fully compressive yet comfortable bicycling short. Waistband has 2/3 elastic band, covering the entire back and sides, ending at the pelvic bones for less restriction on the abdomen which allows for a more comfortable stomach area, alleviating the need for a drawstring. It also helps to avoid common GI issues. These shorts come with two side leg pockets that will keep all your belongings from shifting or falling out. They are large enough to carry energy gels, credit cards, keys, or a cell phone.
