Exped SynMat 9
Here's what other sites are saying:
The SynMats don't have the same insulating properties of Exped's DownMats but they do offer the same comfort, in a lighter, more compact size. Synmats also come in at a lower price point since synthetic fiber is less expensive than the goose down found in the DownMats line. The weight to warmth ratio is far superior to standard foam filled sleeping mats.
