Does B2 Mask fog my glasses?

Does B2 Mask fog my glasses?

B2 Mask is designed with a flexible seal that eliminates or significantly reduces fogged glasses. If you are experiencing any fogging, you can try flipping the nose seal portion to achieve a tighter seal on the nose. 

Alternatively, nose seal may be improved by switching the B2 Overlay 3D Knit, which has a metal nose clip, or by inserting B2 Mask Liners inside the mask.
