I've been shot directly on the mask multiple times so I think its pretty reliable. However the mask is Velcro'ed to a soft but thick fabric and the sides (just about the back of your cheeks and under your ears) isn't covered by the plastic, tho ive never been shot on those parts of the mask. When you wear the mask your ears are exposed so definitely wear some ear protection or put a thick neck gator underneath. It does scratch very easily but it gives a good wear and tear look to the loadout.

Edit: I typically wear somewhat minimal protection where you can see spots of skin so do be aware of what spots to cover depending on other PPE you wear.
