Ian Ogilviewrote a review of Backcountry Merino Bliss Lightweight Long Underwear Top - Men's on January 10, 2010
I'll chime in. Aside from the great qualities others have mentioned, for me this is an outstanding shirt. I"m 6'4" 185lbs and got the XL. It's somehow is skin tight but not constricting at all. The arms are long. I can use the thumb holes without feeling like I"m cutting off my circulation. The shirt is long and stays tucked in. Pure luxury.
