Nice breeze inside your mask, noisy
The mask fits quite well, it is heavy so kind of ends up feeling heavy on the bridge of your nose and blocks mine a bit. To compensate for it slipping Ive had to tighten it around the back of my head with the velcro straps. The airflow is great, when my face gets hot from wearing it and I put it on its high setting I can feel a cool kind of little breeze which prevents me from panicking so really works. The material is really thick and I'm not sure if you could wash it a lot once you take the fan off. Only thing I don't like is that it's quite noisy. On high it sounds like an angry wasp n is off putting. I bought it for use in lectures at uni and it's too noisy for that.
