From Mantel’s point of view, I find it very regrettable that the service in cases like this is so disappointing.

- Ed, 28 July, 2026

I’d expected better from the Castelli brand, especially after the previous pair of bike shorts I’ve owned. After 1½ hours of cycling, my genitals are completely numb. The shorts can’t be returned because they’ve already been worn. In other words, you’re buying a pair of shorts for long-distance rides on a wing and a prayer, and if they don’t work out, you’ve simply wasted your money.

Pros & Cons

None
Doesn’t fit properly after biking for a while
Your genitals go numb

Top trousers

- Henri, 26 July, 2026

Lovely chamois shorts; I recently did a 160km ride in them without any problems. The legs are a bit on the long side, sitting just above the back of the knee. The shorts are quite tight-fitting, which I like. I’ve got the blue ones – a lovely colour.

Pros & Cons

Fits perfectly
Good chamois
The legs could have been a bit shorter

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

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)
