I want to congratulate you on your products. I bought long sleeve and a short sleeve T’s and your sport socks after reading about them in Tree Hugger. I really wanted to know just how viable “Bamboo clothing” could be. WOW!! The only other time I was this amazed was when I found an Italian Merino wool shirt in a discount store! These items are so light! Layered, the long sleeve T is great under a heavy cotton sweater I have. I had no problems staying warm in sub-freezing weather with a basic coat on. The sport socks are very cushy and work well with my moccasins. I am in the market for more.
