User Review: Therm-a-Rest NeoAir
Price Paid: $170
I waited until the large size was released, which is 5" wider and 6" longer. Suffice it to say that this mattress is incredibly comfortable and provided the best sleep I have ever experienced on a backpacking trip.
Sleeping on your side is no problem with the NeoAir. It is also super light and packs down to the size of a small loaf of bread. I was able to carry it in the sleeping bag compartment of my pack along with my bag. I will never sleep on anything else.
The only caveat is the painful price, but a comfortable nights sleep is almost priceless on the trail.
