Product feature
  1. Our tips for use:
    "We can't say it enough: undershorts are worn without underwear. Surprised? With underwear, you are more subject to chafing and shearing... All combined with perspiration (heat + humidity): this is quite the recipe for infections. If you haven't tried it yet: try your undershorts without underwear, you'll be convinced!" Daniele, Rockrider mountain bike product manager
  2. What is a "mesh" fabric?
    Mesh fabric is thinner, lighter, and more airy than cotton or polyester fabric. This breathable fabric wicks away perspiration more quickly. This material doesn't leave a damp feeling on your skin that can give you chills while cycling, making the undershorts more comfortable to wear (feels like a "second skin").

  • 500 mountain bike undershorts

    Adrian (United Kingdom)
    Used for 2 to 8 weeks
    Well made, right size, comfortable, so far I have worn them for short distance, no more then 30 km.
  • Reasonable Value

    Martin (United Kingdom)
    Used for 2 to 8 weeks
    Purchased to wear under MTB shorts with a view to changing into clean outer clothes after riding.
    The mesh layer is pretty much transparent so not ideal to be changing in public car parks.
  • High quality undershorts

    Used for 1 week or less
    These are very comfortable undershorts. I use them as baselayer for road cycling as the meshy feel is superior to cheap cycling shorts. As for sizing, I always go 1 size up when buying decathlon gear.
  • Great product

    I loved it...Very comfortable for long distance cycling. Permits blood flow to the groin area, which otherwise gets blocked. Superb product
