This is a new one for me, for many years I have used a therm-a-rest long wide self inflating pad. This was a great pad, warm and comfy.
As time has moved on pad technology has changed for the better and the Synmat exemplifies that, its light, comfy and to my surprise, just as warm. The major upside is the weight and pack size. The long/wide version which I got is half the size of the them-a-rest.
I did get the EXPED Schnozzel PumpBag which inflates the pad in less than a minute and also acts as a dry bag (got to love multi use items).
For my size and weight (6’2, 240lbs) this pad was very very comfortable!
Light weight and small pack size.
Easy to inflate.
Comes with repair kit.
Quite (unlike some inflatable pads).
So far none!
