Run, Swim, Or Ride 400 Miles And More In These Durable Shorts

The De Soto Men's 400-Mile™ Cycling Short was given the "400-Mile" name from product testing consisting of 400 miles over 4 days. De Soto's 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.

To construct the incredibly durable 400-Mile™ short, this 11-panel short utilizes Forza Compressor fabric to ensure a perfect fit. Targeted muscle support meets Curvilinear™ seamless and contrast flat stitch highlight panel construction for an incredible ride. The 14mm 400-Mile™ Pad was sewn into the short instead of on top of the short. This slight difference allows the pad to stretch more as well as float, so it can be used as a race piece in a triathlon to boost you ahead of the competition. 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.

A Mobius Strip is a surface with only one side and one boundary. Mobius™ Comfort Compression leg bands are De Soto's new form-fitting, yet non-binding compressive fabric. The knit was created when blending fibers make repeated Mobius loops so that the same surface, stretch, and rebound is on both sides of the fabric and in equal direction. You'll notice comfort and support without constriction, opacity without unnecessary weight, and durability from a very smooth surface on both sides.


  • The 14mm 400-Mile™ Pad is sewn into the short, allowing the pad to stretch and float so it can be used as a race piece in a triathlon

  • 11-panel bike short made of Forza Compressor fabric ensures a perfect fit, and targeted muscle support
  • 3-inch Mobius™ Comfort Compression leg bands keep shorts in place without excess squeezing
  • Hi-rise, elastic waist and adjustable drawstring keeps the short up and protects you from low back sun exposure
  • 3 pockets, one on each outer thigh and one center back pocket
  • Curvilinear™ seamlines and contrast flatstitch highlight panel construction for extreme durability
  • This environmentally-friendly innovation is completely free of solvents
  • Not recommended for repeated use in a chlorinated pool
