If you're looking for a mat that can hack all four seasons especially the dead of winter consider the award-winning Exped DownMat 9 and 9 Deluxe. The 3-1/2"-thick mats with down insulation effectively stop the heat-robbing ground from getting to you. Lightweight and compressible, they roll up to a pack-friendly size, a huge plus when repacking to get back on the trail. Both come with an integrated pump for faster inflation/deflation time. Imported.
