Familiarity: I've used it several times
This is now my new go to winter tights. I rode down to 20F with a base layer and jacket. Good alone for high 40s to low 50s. You need to size up. I'm 5' 10, 202lbs. A bit expensive but worth it. When you first put them on they feel tight, but once into a biking position (over the bar) they feel great. I'd buy them again.
