Product Customer Reviews

I've been eyeing these pants for a while and now ordered them. I have already tested these extensively. I can recommend these MTB pants. Price performance fits this product.
very good pants, cut, size, material at the bottom of the legs good... however tested this morning during a 4 hour outing with 9 low degrees, fog and 98% humidity, I quickly sweated under the pants... which allows sweating to escape with difficulty I find… to see in colder weather what it gives
The material and workmanship are great, but: 1. Quite a high crotch, it can cause pressure when sitting 2. Size on your knees.
size problem, I priced size L and it's too small at the waist, I barely tried it on, I'm thinking of changing it for a size XL. On a daily basis I wear M or L depending on the brand.
Pants look good and fit wonderfully. However, it could be a few cm longer.
Great product that rivals big brand pants, at a very reasonable price. Very flexible, resistant, and waterproof!
I've had these pants for over 2 years and I've been doing almost all my outings with them for 6 months. Very comfortable, well cut, not too hot in summer, good heat retention in winter and effective in light rain and snow. Flat, concerning the resistance. In 6 months, it's the 2nd pants that I pierce in several places. In a bit committed Enduro, we tend to scrape branches and stones. On the 2 pants, holes at the back due to the heavy with the saddle and at the front with the vegetation and the ground. With more resistance, this would be the almost perfect pants for the price.
Not waterproof
no complaints
very good and solid as well as breathable and shape designed for sport so nickel
Really pleased with theses, and only comment maybe should have gone for the next size up as they are 'snug' . It maybe due to the fact that I like my grub too much. The fir is great and there is plenty of flexibility & room underneath for knee / shin protectors if they need to be worn. High back helps keep vital organs warm. First outing was for around22 miles & they were well comfortable
Excellent, I really didn't expect some rockrider pants. recommend
Great pants for a great price. They are not ideal for rainy weather, but they are quite sufficient for wet conditions.
I bought these pants with 1.65m/65kg in size "S" and found out after using them that the cut in the hip area is completely unsuitable for cycling. Far too tight in the crotch, the 2-way width adjustment is out of place, the zipper is too short, but the material is good. maybe suitable for a child's hips or as a women's model, just unwearable and therefore, because it can no longer be exchanged, thrown in the garbage.
Does the job

What is a water-repellent fabric?
Water-repellent fabric allows water to slide over its surface and delays absorption. This means that the fabric doesn't become waterlogged, but stays light. Water repellency is obtained by applying a treatment to the fabric's outer surface. HOW DO YOU PRESERVE WATER REPELLENCY?The water-repellent treatment applied to the fabric's outer surface needs to be reactivated throughout the product's life. Our advice:regularly apply a fabric waterproofing liquid (or spray)
The cut
Fitted cut: they are closer-fitting at the waist. The stretchy fabric guarantees ease of movement. Wider on the thighs and knees so you can wear both undershorts and knee pads. They are tighter at the ankle to avoid getting in the way of your pedalling.
