After years of gear testing, it's rare that we get excited about new gear updates, but after learning of Therm-a-Rest finally pulling the trigger on updating their valve system, we got pretty excited. The XLite was a recipient of this new winglock valve, as well as a boost in R-value. The 2020 XLite exceeds our expectations for an ultralight backpacking sleeping pad and thus once again takes the Top Pick Award in the Ultralight category."
