I use this mask while cutting 5 acres of grass. I bounce around a lot and I can say the seal is very good. As far as comfort I don’t get any marks from the mask after hours of wearing it. There is plenty of room within it does not feel cluster phobic at all. The over all quality is really nice and seems very durable. I water 6 months to leave this review. I would purchase again.
Wow! Love this blazer! Got it this morning and wore it to work today. So many compliments! The quality feels great too! It’s lined and has two pockets. Fit was true to size. Very professional looking, yet comfortable. Would definitely buy again!
