Fits nice overall, but the zipper...
The Castelli Nanoflex legwarmers contain a fleecy interior as well as a waterproof exterior. Being that these are snug, the silicone grippers do irritate my skin a little bit. This is from the friction of the grippers with my skin. Slightly uncomfortable after a long ride, but being that they feel comfortable otherwise, I don't mind too much. The irritation really sets in after these are removed. These legwarmers are a bit on the glossy side, as with the arm warmers.
Additionally, since these legwarmers (or being that Castelli products generally run smaller), the zipper digs into my ankle. I'm not sure if going a size up would make all the difference. It probably does, but oh well! I like what I have.
