Bamboo T-shirts are the greatest shirt I've ever worn. The material is silkier than cotton, they wick away sweat, stay cooler when it's hot and warmer in colder weather. Aside from a slight shrinkage, I wear this shirt to work, to play and to bed. If the world all wore bamboo, we'd all be touching each other. Maybe people would smile a little more. Full review
