Purchased for my eldest son whom works in the environmental field. He said he loves the protection and comfortable fit.
I was happily pleased to see all the debris that it kept out of his lungs. He brought it by when he washed it and changed the replaceable filter.
He said he would highly recommend.
Excellent and fits comfortably
Excellent durability, very effective, comfortable, and long lasting consisting of quality material.
Worked well at Burning Man. Fairly easy to get on and off. Nice that the filters are replaceable.
