Better than Thermorest
I purchased one of these for my kids to use while camping, but I have used it on a few occassions. It works quite inovatively with Big Agnes bags, but it really is a star performer due to its comfort. blow it up solid then get into your bag. adjust the valve control to the level of air to your liking. I find that once you achieve your level of softness that the pad feels much softer and lacks that air blob feel that my 20 year old thermorest has. definitely worth the money.
