      TECHNICAL INFORMATIONS

      In a nutshell

      Pad thickness: 13 mm
      Pad density: 100 kg/m3
      Pad firmness: 25 KPa

      Undershorts support.

      Bibless undershorts can be much more practical. But do you get enough support?
      To guarantee the support you need, even without straps, we have made a pair of undershorts that hugs your body just like boxers. The elasticated waistband adapts to fit you and stays in place with no adjustment needed.

      A SECOND SKIN WITH COMFORT TO BOOT.

      The pad has been designed for more regular users looking to progress in MTB. The support foam is also soft but more dense. It protects pressure zones for up to 3 hours. The foam is soft and the stretchy outer layer hugs the cyclist's body so the pad can follow their movements.

      Foam thickness: 13 mm
      Foam density: 100 KG/m3
      Foam firmness: 25 KPa

      Shorts, undershorts.

      Undershorts are to MTB what kilts are to Scotland: you wear them against your skin!
      To avoid chafing, we therefore recommend changing them and washing them as if they were underwear.
      And when you're riding, your shorts and undershorts should never be attached.
      Why? Because each has their own role to play:
      - The undershorts stay in place for comfort and support.
      - The shorts move with you for better freedom as you cycle along.
