Yes it's light weight. I haven't tried on the snow yet. But what I don't like that is bit to narrow, every time you changing position you have to wake up to not fall off. And it's slippery whit modern sleeping bag. Also inflation valve is just one of those things engendered by those who never use it.
Small, light and does exactly what it says on the tin! Great piece of kit!
Love it. It's the best matt iv ever had . Light eight small pack size and really comfy to sleep on .
