I bought the earlier version of this mattress in 2002 and it lasted until 2010..VERY heavy use, constantly being packed and unpacked, extremely robust..never got a puncture. Before I got this mattress I would wake in the morning cold and stiff, and have to potter about really slowly until my body came back to life, but after I got the mattress I needed only to wait until the coffee was circulating in my veins to be ready to go. Also it kept me warm..before (with the same sleeping bag) I would have to wear all my clothes at night in order not to freeze, after I got it
I could manage with just half of my clothes on..
I foolishly replaced this with the Thermarest Neoair, which was a stupid thing to do, because this product is Much more reliable and robust, PLUS it inflates itself, though it may need a couple of puffs of air if you like it to very fully inflated.
