I heard from the Manager of a local sporting goods store that all current models of the Xtherm and other Thermarests are being discontinued so that the 2020 models will all have one way air valves and a couple other upgrades. Apparently, Thermarest was getting their market share taken away by Exped and others for not being as user friendly.
As a result, most Thermarests are -25% off at places like Moosejaw.com.
