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


Undershort support.

The pad has been designed for regular users who want to improve at mountain biking. The support foam is soft and dense. It protects cyclists’ pressure zones for up to 3 hours. The stretchy outer layer hugs your body so the soft foam pad moves with you.  
Foam thickness: 13 mm (1/2")
Foam density: 100 kg/m3 (6 1/4 lb/ft3)
Foam firmness: 25 kPa (3 1/2 psi).

A base layer with added comfort.

bike shorts are to mountain biking what kilts are to Scotland: you wear them with nothing underneath!
To avoid chafing, we recommend changing them and washing them as if they were underwear.
When you’re riding, your shorts and bike shorts should never be attached.
Why? Because each has a different role:
- The bike shorts stay snug against your skin for comfort and support.
- The shorts move for better freedom while cycling.

Shorts, bike shorts.
