User Review: Exped DownMat 9 DLX
Price Paid: $200 NZ
This is singly the most comfortable, and warmest sleeping mat I've used, and I've been through quite a few. It takes the lumps and bumps out of rough ground, and is great on any surface.
However (and this is the only reason it gets 3 stars instead of 5), on a recent 25 days continuous use (in huts and shelters) on the Bibbulmun Track in Western Australia, about half the internal dividing baffles delaminated from from the outside of the mat. This meant it ended up being round rather than flat. I have taken it back to the shop I bought it from, and they are looking into it.
