Therm a Rest RidgeRest Solar Sleep Pad

It's hard to improve on a classic Ridge Rest, but the folks at Therm a rest have managed to do it with the Ridge Rest Solar Sleep Pad. With an engineering feat that will keep the folks at NASA up at night scratching their heads for years to come, the Ridge Rest Solar weighs about the same as classic Ridge Rest, yet actually retains more warmth. How'd they do it' By adding a new aluminized coating to the surface of the pad, the Ridge Rest Solar effectively radiates body heat back to you instead of letting it dissipate away, thus making it 10% warmer than traditional closed cell foam pads.
