...compared to original NeoAir
I actually prefer the original NeoAir to the XLite that replaced it. Yes, the Xlite is 2 oz lighter, (regular size) and has a higher R-value of 3.2 to 2.5, but the edges of the XLite pad collapse under load and make the pad feel narrower than it is. The original does this as well, but the straight corners make up the difference. I'll stick with the original!
