All our baselayers act like a second skin. Extremly slim fit cut with extended back side for lower back protection. Whatever Isadore jersey size you are used to wear, this baselayer will certainly fit you in the same size. However if you prefer more casual fit, we advice you to choose one size bigger than the Isadore jersey you are used to.

Awesome
About the fit: I gained some weight after I bought this a few months ago. Sort of ironically, training made me gain weight -- mostly muscle weight. My height is around 5'4''. Isadore size XS tops (women's) are a tad loose when I was about 115 lb, but when I gained weight to over 120 lb, they fit quite perfectly. I love this baselayer. I sort of felt it at work in hot weather when I sweat profusely. Like my sweat evaporates so quickly.Show full review -
Alternative Long Sleeve
This is my comment to the long sleeve shirt: It is thicker than the short sleeve summer shirt. It feels very nice on the skin and protects very well on cold rides with a long sleeve jersey. I am 188cm/78k - chest 100cm and ordered XL it sits nice on the body without being tight. The sleeves could be 2 to 3cm longer, but since it is a base layer it works as is. I'd purchase an other one right away.Show full review -
