2020 Thermarests with Wing Lock (Uberlite, Neolite, and Xtherm)

Just for info, I’ve been using the Uberlite with a 1/16″ EVA pad under it on a DCF floor with polycryo under that.

The leak developed about 1 – 2 cm away from the edge of the wing lock valve, where the fabric material forms a lip that goes around the pad. Given the placement of the leak and the care I took with use, it seems very unlikely that it was caused by a puncture. I’d bet almost certainly that it was due to material failure, but I didn’t try to deal with warranty service (which in the EU generally isn’t as proactive as what you’re used to in the US).
