It always feels like a gamble buying a new duvet but with this one I felt very confident in buying because of the 30 day trial period (only available if you buy online).  You just don't know until you've tried it for a while if it's going to be the right duvet for you, especially when it's made from a 'new' material,  in this case bamboo.   So far, we're very happy with our Panda Cloud Duvet.  Very light and warm, easy to handle and looks nice on the bed with a duvet cover.  I like the square sections which make it lie tidily on the bed - no lumps.
