Shipping was very fast! These came about a week earlier then expected. I ordered based on the Kerrits size chart and got a small (Im 54 and 120 lbs and usually a size 3 or 4) however they feel very snug! I had a hard time getting them all the way up my legs (but to be fair I do have pretty big/muscular legs) since most riders have strong legs I didn't think I would have to worry about that making a difference.
 Im going to keep the small but if I order again in the future Ill get a medium.
The material is very weird, but it works! It feels like my fleece lined leggings that I have, so it threw me off that these were supposed to keep me cool. But they did! I live in the Midwest so our temperature go up to high 90s with LOTS of humidity and I stayed cool my whole ride.
