Thicker than baselayer shirt.

Like another reviewer, I'm 5'11" also of a slender build and was very pleased that the length of these - pretty much went from pit to wrist. Ran this morning and the cuff over the wrist covered better than my baselayer shirt that leaves that annoying gap between my running gloves and shirt. For me, I find my core warms up pretty quickly on a run and these are perfect for my arms that seem to chill easier.
