This stellar short is an improved version of the 400- Mile™ Bike Short of 2008 with improved fit, comfort and most notably, our new Compressor™ (see Fabric Facts) double legband. Your hamstrings and quadriceps will thank you for the incredible support. Newly innovated 400-Mile™ 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. This 11-panel bike short has a Carrera™ Piqué Abdomen panel and piping for added comfort and flexibility on long rides. Drawstring elastic waist, Curvilinear™ seamlines, contrast flatstitch, and the 400-Mile™ Pad make it the most comfortable short money can buy. It has 3 pockets (one on each leg, and one in back) that fit cell phones, mp3 players, fuel packets, and most sunglasses. One of the great features of this short is what it does not have…no leg gripper, so there is no tight binding around the thighs. The short stays down and in place since it is made of Forza Compressor™. Emilio gave these shorts and bibs the "400-Mile" name from product testing consisting of 400 miles over 4 days. His logic was that many shorts feel fine for 100 + mile rides. The real question is how does that saddle feel when you get on the bike the next morning for another 100 miles...and the next morning? This was the inspiration for the design, the pad, and the name. Note: This item is not designed for repeated use as a swim suit in a chlorinated pool. Sizing Chart
