This is a very thin layer. Merino wool is great natural wicking layer. Best worn next to the skin.
I purchased a medium, but it runs a bit short in torso length. I�m 6.0� and 180lbs, a large would probably fit better.
I love this base layer. Tight-fitting and cut well to fit under bibs. Super warm--a great foundation to layering for colder rides. Add a long sleeve jersey in the fall and then throw on a vest or jacket as it gets even colder.
