Pros & Cons

Pros & Cons

  • The Progetto X2 Air seat pad provides comfort and breathability.
  • The Forza2 fabric reduces drag and increases speed.
  • Thanks to the mesh bib straps and the breathable fabric, this bib short is absolutely suitable for your summer rides.
  • The Forza2 fabric may feel rather tight for the recreational cyclist.

Fantastic

- Jules 24 July 2026

Castelli trousers really do stay looking great; I swear by this brand. The chamois in the trousers stays in good condition and soft even after washing, so for me they’re top-notch. Do go for one size larger than you’re used to, though – but I already knew that.

Pros & Cons

Great trousers
The chamois pad is brilliant, especially for long rides
They fit brilliantly

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)

Fine trousers

- Pieter 2 October 2025

Trousers fit fine, slightly roomier than the free aero rc old version size L. Fabric feels slightly thinner.

Pros & Cons

Aerodynamic pipes?
Grippers
Slightly roomier
