the reason we use cotton (or organic cotton) as a blend with bamboo (or hemp) is to get the feel right. i'm told that bamboo doesn't weave well without something to add body to the fabric. it is being worked on and it's likely that we'll see 100%bamboo fabrics soon.
keep in mind that the environmental benefit is huge even when a 70/30 blend is used. even when using organic cotton and thereby taking chemicals out of the equation the irrigation needs are reduced greatly. 100 t-shirts saves 74,395 gallons of fresh water. check out our
