The SynMats feature microfiber insulation for comfort, warmth, lightweight and durability. As the microfiber is very compressible, the mats pack down very small.

The SynMat UL is ultralight and ultra compact, but not as warm as the standard version. These won the coveted gold Outdoor Industry award in 2010. The thicker 9 M and 9 LW are especially warm. The redesigned SynMat Lite (formerly called Basic) are the perfect entry level mats offering warmth and compact packed size. The SynMat Lite UL is the ultralight version which makes them remarkably light and compact!
