Super Comfortable
04 July 2025 by J.a
These trousers are used on the daily; rain, wind or shine. I cannot fault them. The armour is comfortable and provides good coverage and there's plenty of pockets too!

more than I expected

more than I expected, Fabric quality is excellent, the protections seem a little heavy but that's okay, the waist seams are of good quality

Ok but not waterproof
28 December 2022 by Owen W
They fit well and I like the styling, but I bought them as they were advised as waterproof. After half an hour in the mild to medium rain it started coming through. I have an Alpinestars jacket which is perfect but after buying these trousers I'm a bit disappointed.

Overall amazing quality.

I bought these as a lightweight alternative for slow riding and I'd never look anywhere else after getting these. Amazing comfort, very breathable for hot weather and they have an amazing fit. They aren't baggy but they give you tons of room for moving around etc. Just overall great!

Ok

I ordered these as I loved the look of them and when they came i wasn't disappointed with the looks. When they arrived though I though they were very thin. Also I didn't like the tightness of them around my ankle and that made them look stupid sitting above my short boots. So I sent them back and ordered a pair of jeans instead.

Comfortable and warm
02 October 2020 by Gavin W
The material stretches so mounting and dismounting the bike is easy. Windproof and warm you can wear them anywhere.
I ordered the hip protectors separately as the jeans only come with knee protection.

My New Favourite
24 July 2020 by Nick M
Wow...
I ordered these primarily due to the look of them. However having used these for riding over the past few weeks all I can say is that they are the comfiest riding pants I have ever owned.
Incredibly light, elasticated waist and ankle parts. Deep waist pockets, zip leg (with button) pockets.
Seriously considering purchasing another pair.
