Reviewed by Drunkensailor - 11th Aug, 2016 Brilliant Mat I have one of these and it's brilliant. Very comfortable and very easy to inflate and deflate. I have the pump sack which doubles as a dry bag, it's really easy to use. The pack size is very small and light, the mat also insulates you from cold ground and reflects your radiated body heat back towards you assisting in keeping you warm. Yes it's pricey but as the old saying goes, you get what you pay for. In this case that's definitely right.
