"Like anyone reading this, I've worn my fair share of masks during the last year, but these are the worst. The amount of condensation that builds up inside is unreal and after just a few minutes of wear my face is soaked (genuine drips hanging of my nose). It's horrible and in the cold it's even worse. Don't know if these are cheaply made or I got a bad batch but I would absolutely *not* recommend these unless you want a saturated face almost immediately. Horrid."
