I have also bought the mask, but not here at special Bike Components. I have now tested the mask at -15 ° C and was very pleased. Due to the comparatively generous mouth and nose openings you can still get enough air even at great effort. While the tip of the nose and the mouth are a bit cold one is but still well protected - a very good compromise in my view. Very slightly down inside my goggles but then also started - but was not disturbing, only the very end everything is up and running, but as I was then already there.
The material is very thin and not somehow stitched, just below the edges of the top and in the holes. Let's see whether more use there are signs of wear.
