Re: Sizing

The listed is EU sizing, so the US size varies. An EU small is an US extra small, an EU medium is an US small.

Not enough padding

Shorts are comfortable and fit well, only issue is that the padding is to thin.

You get what you pay for

Cheaply made. After tying the waist it ripped the elastic waste band. The shorts don’t ride well. Will be returning them

Surprisingly good.

I wasn't expecting much from these but they are as comfortable as shorts that cost double, highly recommended.

Great shorts, fit wonderfully

I was reading the other comments from India, UK and the Philippines and was very skeptical about this pair of shorts when I aw so many 1 and 2 star reviews. You need to remember that these are UK sizing on the website, not USA sizing, so a 38 is not going to be a 38 waist USA (a 38 UK is more like a 29-30 USA). Anyways, I ended up buying these because the memory foam seat cover that I also bought from decathlon was starting to wear away. This shorts were amazing! I have never felt so good or had such a comfortable ride EVER in the 25 years that I have been riding. I do not like the spandex-type shorts, especially since foam padding makes those types of shorts look very unattractive. These look like board shorts (they are long and will reach close to your knees). The sizing was spot on. I wear 33 inch waist USA jeans, and I chose the 42 S-M size shorts. Many of the comments are totally not understanding the sizing. One comment said a 39 inch waist corresponded to a medium.....um..no it doesn't.. (a 39 inch waist is more like an XXL.) Do not be dissuaded by the negative comments. These are stylish, comfortable, and correctly sized short. If they had more in stock online in M, I would buy more!

good enough

not too flexible, but do the job

Sizing is dreadful

These may well be a great pair of short but I couldn't comment on that. The two pairs I purchased were supposed 99cm to 106cm waist, they were actually closer to 84cm to 91cm so they were returned

Good short

Comfy

Better than expected for the price point

I was a little apprehensive after reading a few reviews regarding sizing but they fit perfectly, so guessing that other shoppers are not checking the sizing guide and ordering waist instead of hip sizes. Overall quality appears to be good and the only downside is that the seat padding is not quite as thick and supportive as other products i've purchased from Decathlon, but for this price they are much better than I was expecting and I will be purchasing another couple of pairs as soon as they are back in stock. .

Sizes are so inaccurate it's a joke.

Ordered a medium as they allegedly fit a 39 inch waist. Couldn't get them past my knees so returned for an XL. Still too small. I can wear them but can't get onto my bike in them as they are so tight. I think you really need to work with your suppliers to get more accurate sizes. Really annoyed at the hassle. Avoid!

Watch Sizing Guide - HIPS not WAIST

Make sure when you look at the sizing guide you measure your HIPS and not WAIST. No idea why as this is the first time in 35 years I've ever seen men's shorts/trousers measured in hips and not waist! Needless to say I ordered the wrong size!

Cycling shorts, the mountain bike rider's kilt

Don't forget: you wear cycling shorts without underwear. Why? Wearing underwear risks causing irritation. Your skin can rub against the seams and elastic of your underwear. Chafing, shearing, all combined with perspiration (heat + humidity)... this is quite the recipe for infections. That is why we design our shorts with anti-bacterial pads. Dare to wear shorts without underwear!

Our care tips

Machine wash inside out on a synthetics cycle at 86°F. Do not use too much detergent, and do not use fabric softener. It is best dried on a hanger in a warm, well-ventilated place.
