John Baker wrote a review of Airblaster Merino Wool Ninja Suit - Men's on January 6, 2011
Jackie Chan has nothing on this sweet outfit. The ninja suit makes a great base layer; soft and really warm for as thin as it is. I wear mine when I'm battling evil warlords, and when I'm just sitting around the house watching tv. I'm 5' 8" 145 lbs and the Small is perfect/snug fit for a base layer, but if you're much bigger I would go with a medium.
