Good mask, but poorly ventilated.

Pro:
+ Good comfort
+++ Crystal clear view
+ Easy to clean

Contraindications:
- In combination with the 6200 half mask 3M goggles sitting too high up
- Very lousy ventilation
--- Condensation in cold rooms!
- Quite hard seal

The comfort is good, the glasses sitting comfortably and the rubber band has just the right elasticity. Combined with the 6200 mask 3M unfortunately a bit too large, the glasses rides up. Even the quite hard seal transition can interfere, in my case, but this fits exactly.

The disc is ideal. You can tell almost no idea that you have the glasses on. No distortion, no reflection, no! I was thrilled when I first had the glasses on.

Now the crucial point of criticism: The mask is not ventilated. Since you (if done correctly Works ;-) quite strongly sweats in the face, to principle Due forms a vapor layer through the sweat. And this then condenses on the lens. Depending on the welding development and ambient temperature, the glasses after a few seconds or minutes (!!) is so fogged that one sees nothing (!) More. Since I agree with the previous speaker on unconditionally. So if you work for a few minutes and heavily sweating and it's cold in the area, you have to interrupt your work and settle the glasses.
The glasses are tight, which means you irritate his eyes even through gases / dust from the environment. In my case, but a vented goggles, for example with foam filters would have been better.

Thus, if you plan to perform strenuous work during the Cold (shell), this mask is not recommended. For a bit of flexing and work in the leisure sector, the mask was good enough and provides good comfort.
