Very good

This is the second one I have bought and I bought a size larger because the size I usually wear was too tight on my thighs. It works very well on journeys of 2 to 3 hours.

Not recommendable

The thigh waistband is much too tight. It cuts off the blood supply to your legs. It doesn't fit the upper waistband at all in terms of proportion.

Size small

Good product to try for 100 km but the problem is that it's really small, take a size larger.

Pad thickness: 13 mmPad density: 100 kg/m3Pad 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 mmFoam density: 100 KG/m3Foam 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.
