Road cyclist. I am 6' and 180 lbs. Bought a LXL, but it was too tight. The mesh gave my skin a waffle appearance. It could use a bit more give or flexibility. I have an old Defeet base layer which is much more comfortable.
FIRST TIME I BOUGHT A CORE SHIRT...THE PROBLEM I SEE IS IT COMES ONLY SM or LXL...I REALLY NEED AN M .
IT GOES ON VERY TIGHT AND I NEED HELP TO TAKE IT OFF...IT REALLY IS SKIN TIGHT ON MY 62 KILO 5'7 SKINNY FRAME....I'D BUY A REAL MEDIUM BUT IT DOESN'T EXIST IN CASTELLI (MY FAVORITE BRAND)
