Are good, but hard to fit a respirator under one. THey are nice because,, although they are cumbersome, and may steam up in rainy weather, they protect you from a lot, even with eye wear, I still get dust in my eys, which is the worst thing to have to deal with when driving home, after carving all day. Tyvek makes a helmet that has a respirator fan attatchment, Baileys has them, they can run over $100, for the head gear, but you'll be able to see, and breath really easy. You can get the full suit for around $150-$200. Very ideal for carving cedar, and for spray painting.
