This is the most premium 100% GOTS certified orangic cotton t-shirt in the market. We took ring spun combed organic cotton yarn and knitted it into the perfect weight t-shirt. Not too thin - not too thick. At 8oz (170gsm) - this is the ideal all season staple. And with the added pre-washing and enhanced shoulder taping - you'll feel the difference every time you put it on. Canadian 8oz/ USA 5oz | 100% Pre-Washed Organic Cotton UNISEX FIT - Women may want to order one size smaller. MADE IN CANADA
