For a mat of exceptionally high-quality, yet affordable price tag – you can’t go past the SIM 3.8 M from Exped.

The SIM 3.8 has an R-value of 4.6 so you’ll get some decent insulation and warmth from your mat, and it’s cushiony enough to actually keep you comfortable while you snooze. The single combination valve on the SIM 3.8 allows you to inflate and deflate with just one valve, and the comfortable slip-resistant surface won’t rub against your skin. Those Swiss really know what they’re doing when it comes to design, so you can trust that the folks over at Exped know a thing or two about how to keep you comfortable out in the elements.

The SIM 3.8 M from Exped is compact, and a perfect size to slip or attach to your pack for a hike, or to pop on top of a stretcher for camping.
