Easy breathing and uncrumpled filters but misted up specs

Without the “snout” the filters crumpled up inside the pocket. The snout fixes that but the seal at the bridge of the nose hasn’t been a easy to achieve because the snout comes up quite high. I haven’t tried very much to solve that as I am mainly at home or popping into shops for three minutes and wear the mask without the snout.

I must put this in context. I am reviewing the snout that you put inside the mask to keep the front of the mask more stretched out. The masks themselves are fantastic, you can get a great seal all around to the extent that no air escapes around the edges, not that I can feel anyway. Brilliant.

Doesnt do what it claimed

My mask slipped off my face almost as soon as I put it on so the crew at Petit Pli sent me an 'upgrade' which is a face shaped plastic mould which needed to be sewn into the mask. The mask now does stay in place but of course the reason I bought it in the first place was to have something that I could wear around my neck and pull on and off as needed. The mould makes this impossible so this mask is no different from all the other masks except this one is too bulky to even keep in my pocket.
