4 / 5

Top trousers, but the noble parts at the front deserve a bit more coverage ánd better positioning

- Arnaud 11 October 2025

The fit and finish of these cycling shorts are excellent. However, the chamois does not provide sufficient coverage of the soft tissue areas, leaving these areas exposed to airflow and viewing. In warm conditions, this may still offer some ventilation benefits, but in cold air, it leads to discomfort and insufficient thermal protection. An extension of the chamois at the front, as applied to other cycling shorts, could remedy this problem and significantly improve wearing comfort.

Pros & Cons

Comfort with thick chamois
Permeable fabric ideal for summer
Quality
Chamois too short at the front
Colour mocha does not easily match other colours
Price on the high side

4 / 5

Fine trousers with comfortable chamois.

- Jeroen S 3 October 2025

Wanted something different from the semi loose chamois from assos that seems to shift a bit on my slightly crooked body anyway. This is a nice alternative. Bib straps could be a bit firmer and fit is okay but not super. Most important for me is the chamois. It is good. Not too thick not too thin, gives good comfort.

Pros & Cons

Deep black colour.
Good chamois
Bib straps are of somewhat limp material (compared to assos)
