Have used the Neoair now on three overnights in the northern Colorado mts. Has kept me warm and comfortable in rainy 40 degree temps. It is a big advantage in comfort over a closed cell pad or a thermarest and much lighter that other air matresses. I am 6 ft but use the small size to save on weight and bulk (using my pack for my feet and lower legs) Put it in tiny stuff sack a Sierra Design rain shell comes in and save $15

i just finished up a stint with the size small of this pad racing tour divide. i must say i was quite pleased. i expected it to be more fragile than it is. no puntures or slow leaks. it is narrow but surface begets no slip issues so width is less of a factor, particularly if you drop the pressure appropriately on it (think tubeless tires). for multi-day ultra racing, i would not use anything else. uber compact! thanks thermarest.
