Product Reviews


I am very pleased with the service Decathlon provides and the quality of their products.
As others have said, the latest (2021) version of these are sized/cut for a child with a beer belly! OR a stick insect. Dont buy without trying on in store. Likely uou will need to size 2 times up and take the waist in. Decathlon, PLEASE fix the weird 'large waist/ultra skinny legs' fit - its mad! I have a 32" Waist, and like the pair of these I got years ago bought Large, which used to be for 82-89cm and fitted well32-34". The latest version Large MT900 now state on the label they are for 99-106cm (38-41")!! However, despite the claimed size I could barely get these on, they are so tight around the thighs and bottom, my legs started throbbing the legs were soooo tight. And I have a slim athletic shape legs/bum - not a 'Chris Hoy' figure. riends keep telling my I need to eat more and put on weight, so its not my shape, but these new cut of the shorts. The waist might just at a push stretch to 41" - but there is no way anyone with that waist would get them above their knees. The shorts themselves (my last pair) are excellent otherwise - the pad is fabulous, comfy, not bulky, light, doesnt get smelly. Such a shame they have totally ruined the cut. I am going to have to try an XL (for a slim build & 32" waist!) in store and hope I can then take the waistband in - as they are otherwise great undershorts. Maybe these were a mis-manufactured batch - however I also have the excellent and great value MT500 undershorts - and also an old pair - and its exactly the same issue, infact, even worse on 2 pairs of those I bought. You would need absolutely pipe cleaner legs, no bottom and a huge waist for the cut to have the correct snug but comfy fit.
Comfy for long rides
Very good fit, nice flexible material, pad comfortable with no rough seams. Only slight negative (though not enough to make it 4 stars) is that the padding is fine but may not be enough for a day in the saddle in rougher terrain. But hey, I'm being picky.
Good all round product
I have had good experiences with Decathlon products before so decided to try the under-shorts. Unfortunately none in store, I had to order online. I told Decathlon I was 36" inch waist (I am in fact 34") and they said I was size large. Product arrived and they are VERY snug, I am athletic and not a large build but these would only fit those with a stick insect type figure. So size up ! I also found there is a gripper on the legs, which I specifically asked about as I do not like them, again I was given bad information by Decathlon customer service. Advice; only buy Decathlon products in store where you can see and try on before buying and if out of stock, go elsewhere.
Good fit and style. Plenty of padding. To wear under mtb style shorts.
I've tried padded shorts and padded undershorts from other shops but these are the only ones that I find comfortable. My biggest problem with other makes is chafing at the groin/very top of the leg - these are sufficiently wide and padded to avoid that.
Bought for partner but returned. They looked great, fitted well/snug but he found them uncomfortable with the gel pad seating. I guess it’s something you get used to.
Never actually worn them as I used the size guide to order them and when they arrived it turns out the size guide was wrong and couldn't even get them on. However they do look really comfy.
Comfortable good fit, well made.
Padding helps so much!
Bought these to try out the B'Twin pad before deciding on which bib shorts to buy. Several hours in the saddle and (with a bit of chamois cream) no problems at all. May stick with these and unpadded tights for a while.
Well padded and good fit
Nice
