Rz Mask 265-0070L Rz Mask Lrg M2.5 Mesh Blk

I got the M2 and M2.5 to try out in medium. The amount of material towards the top of the mask is so bulky that it causes the to push up against my glasses. This, in turn, causes the mask to be pushed down my nose to the point where it pinches on my nostrils which makes it very difficult to breathe. This is with the smallest size available. Unfortunately, due to understandable reasons, I can't return the product so I'm not really sure what to do with them now. Just be aware that, if you wear glasses, you may want to pass on these.
