Re: bamboo vs. bamboo fleece
Bamboo fleece and bamboo terry have stretch in one direction (terry more so than fleece). The only bamboo woven fabric I know of is bamboo flannel. Fleece and terry will be a little bulkier but more absorbent than a flannel flat of the same size. I think any of the 3 options would be a good choice.
