As it says on the tin.
Size chart for Decathlon is way off from what the B'Twin packaging showed. I went for a small as I am about 37" chest, which according to the Decathlon Size guide says It's between 36-37.5" (92-95cm). The packaging showed it was 35-36" (89-91). But its fits, compression tight! Which is what I really like anyway. Does a great job to keep cool and wicks well. No problem with seams, as they are not flat-locked. Decent length too.
This base layer is a wee heavy dillion topper. Reasonably priced & good for ventilation under the jersey. Especially when you've got a bit of the beef on you, like me.
Just bought myself two of these bad boys and can't believe they are only a tenner!!!!they fit very nice and keep you cool and dry, why buy expensive castelli when this base layer does the bizz!!
Good fit, comfortable.
Great value, does the job for what it’s intended for.
