Great shirt for lots of things
This is a nice all-purpose shirt. I bought it in a size large, and it fits for me like a typical long sleeve T-shirt. While the blue is not as bright as the picture on backcountry.com's website appears (not necessarily a bad thing), my wife gives this shirt the thumbs up for being a nice looking, casual, non-technical appearing shirt that can be worn around the house or out and about. This is a 260 weight shirt, so it runs on the warm side, making it good for use fall through spring, but definitely not in the summer. One nice thing is that there are are no seams over the top of the shoulders, so this shirt is great when carrying a backpack.
All of the typical pros about icebreaker wool shirts are true for this: stink free, itch free and washable. Just don't stick it in the dryer. My only complaint about wool clothing in general (not this shirt in particular) is that wool does take a relatively long time to dry - certainly longer than synthetic polypro clothing.
