Emilio gave these bicycling 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.
We sewed the 14mm 400-Mile Pad into the short, versus on top of the short. This allows the pad to stretch more, and float; which means it can be used as a race piece in 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.
