I read somewhere that, initially I assume, it gets warmer when first wetted

- um? Certainly, as others have said, it retains some of its loft (sorry) when wet and springs back as it dries. One of the biggest benefits is the lack of need for PPE - damn, it's so good you could almost wear the stuff!
