After the huge success of our 400 Mile Bike Short - both Men's and Women's - we have released a new and improved version. Same great 400-mile pad, same great Forza Fabric, but with added Liftfoil™ fabric to complete a fully compressive yet comfortable bicycling short. The 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.

Newly designed 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 fold over hidden 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.

Fit Note: These shorts are made of our finest compression material, so help fight fatigue. If you want prefer a less compressive fit, please size up. To conform with other product sizing, if you wore our past versions, you will likely need one size larger. Please contact us at, if you have further questions.
