...as to the cottonsherpa/bamboofleece.. the cotton is as absorbant as the bamboo and takes the least amount of time to dry. The cotton sherpa is a less denser fabric, though its thicker.. the bamboo is dense and pretty thin.
The Cotton sherpa looks weird and will feel a bit stiff when you first get it, it will have a smooth surface at first, which will bobble up on the first wash. I love the stuff, some are a bit wary I think, its like cotton fleece just a lot thicker .. its organic and unbleached, I use it for loads of stuff round the house too! Its a great material consiering the cost of it. If you dont like the look of it, you can cover it up
