Works well, keeps you warm on chilly days.
Can�t ask for more.
This incredibly comfortable base layer fits my 5 foot nine inch 165 body perfectly in Medium size. I've even wore it as a casual T shirt on cool days. Definitely a, "Darn I wish I had bought another one when I found this on sale.", when it wears out.
Warm from 40-60 degrees. No moisture buildup. Bought this in my normal size, medium unlike all other Castelli products that I size up.
