okay for Beginners

As stated on the ad for these, they are for beginners. They aren't great at staying up though, as soon as you lean forward to cycle, they roll down at the front so you'll be fixing them at every stop. The pads are good for short distances, I find myself riding 20 to 40 miles though so they're not great for me. I would suggest bib shorts to prevent the rolling at the front and maybe better padding.

Other than Waistband, Product Is Great

I do not understand the negative reviews, as soon after I bought this product my saddle stopped hurting. Quality is great. Waistband could have been better.

Not Good

The main issue is the Waist band which lacks elasticity. The second issue is with the poor density of the fabric - it doesn't stick to a place and one needs to pull up the sleeves often.

Hello Santosh,

We kindly request that you get a refund for the products.


Waistband Is Only Poor. Otherwise Its Great

Recently i completed 365km with this product. I know this product has a lot of hate. But this is seriously worth for it. Only waistband is getting loose after 2 rides. Otherwise its good. Seriously worth for price.

Very comfortable

Good for short rides upto 50kms. One may have to adjust the shorts in between ride.

icon-circle-checkmark verified purchase

The quality of the product is good but only for rides upto 2 hours. For more than 2 hours ride, need to check other products.

Our new medium density pad

To ensure greater comfort in the saddle, we created this medium density chamois pad. The fabric is soft and breathable. The reinforced area is soft, with a density of 220.5 lbs/m³ and a thickness of 13 mm. The material is perforated for improved perspiration wicking. This pad ensures greater comfort on rides of up to around 2 hours

Its shape

The shape of the reinforced (thicker) areas was defined through tests using a seat pressure sensor cover, then designed by our garment designers using a mannequin, then validated through multiple washing tests and field tests. This test, conducted on real cyclists, involves measuring the pressure points exerted on the saddle. The thicker areas are the contact points where pressure is greatest. The dart at the front also lets it adapt perfectly to the shape of your body.

Reinforced areas

The ischiums are well covered, and the perineum is also protected. The reinforced area is relatively narrow between the legs to prevent irritation/rubbing while pedaling. Channels have been embossed into the reinforcements to provide greater flexibility.

Determining the environmental impact of our products.

A product's environmental impact is calculated for its entire lifecycle using various indicators. An overall rating (ABCDE) is given, allowing you to easily identify products with the best environmental performance by comparing similar products to each other (T-shirts, pants, backpacks etc.). Decathlon openly displays the environmental ratings of its products. To find out more:
