I seem to remember these having a few fans on here ? What's the sizing like waist and length please?

I've always found with decathlon stuff that I need to size up from what I'd normally buy. I had a pair of 34 waist Fox trousers that fitted perfectly yet I had to buy an XL in the Rockriders when I wanted a 2nd pair of trousers for when the Fox ones were in the wash

I got mine out of the drawer for the first time this year on Saturday and was reminded at how good they are.  Very slim - the lower leg is spray on, there's enough room in the knees for a slim knee pad but the waist is tight, not uncomfortably so as they're very stretchy but they're obviously building stuff for racing snake type builds rather than short and more stocky.

I quite like them and for the money they're great.

Sounds like I need a 34" waist then @Speeder ?

Fits what @BoardinBob said .

@oldfart - I'm a 33-34 waist measured depending on meals/fitness/time of day/etc, wear mostly a 32 trouser/short. and am 171cm/5'7".  I think mine are a medium and I'd say they fit fine if a little more aero than I'd prefer.  take from that what you will.

For what it's worth the ones I saw in store the other day looked very similar to mine so I doubt much has changed.

+1

Although they are very stretchy, I wear 36" jeans and can just about get away with mine in XL, although I really should go up a size I think. Most decathlon stuff is sized for "real world serious cyclists".  It's not Castelli, but it's more height to weight proportionate than exclusively MTB brands.

They're more like super thick Roubaix tights with strategic reinforcement pads on the outside and just enough bagginess in the front of the upper half to give them a 'trouser' silhouette.

I got some recently. Ended up in the large as the medium were too tight around the thighs.

Mine have no way to tighten up the waist. This wasn't an issue when trying them on as they felt an ok fit. However, on a wet ride it was as they kept slipping down. Wouldn't buy them again for this reason - I'd want something with a belt.

I had the same issues with mine as @jonba
I had to get them in large to fit my thighs but the waist is too big so they won't stay up. I'm a medium in every other brand.

I've got a pair of these in large. Worn twice, once was only commuting. Can't get on with them so going to sell them on. If anyone wants them £35 posted, message me.

These (so we know we are talking the same thing).
