John P.wrote a question about Therm-a-Rest NeoAir Trekker Sleeping Pad on February 16, 2012
Looks great but isn't the R-value lacking? I have a big agnes bag (rated to 15 degrees) and I am nervous that this pad will not keep me warm. I mean a R value of 2 is pretty low. Isn't that equivalent to 35 or 40 degrees?
