Lightweight, very warm , high quality - Therm-a-Rest NeoAir XTherm Sleeping Pad

I have been using air sleeping mat from Thermarest for many yeart, the last one is xlite which is super light, warm and very durable, works well for five years by now. I bought this xtherm for deep winter camping, it is very very warm , just bit heavier than my Xlite. the fabric on bottom is thicker than xlite, so it will be more durable. But I think the fabric on xlite is durable enough lasting for years. Great pad, i love it.
