Review on Outdoor Sports Anti Dust Mask with Activated Charcoal Filter - Windproof Face Mask for Bicycle Motorcycle Riding Ski Ice Fishing Cross Country Hunting - Enhancing Warmth and Air Pollution Protection by Steve Arnold

I am recovering from multiple heart attacks and need a mask to breathe during my rehab training. I like this mask best, except that other reviewers have mentioned that it's for teens and not adults. The amount of material (even at maximum stretch) is insufficient to comfortably fit an adult's head. They should offer an adult mask (longer length to cover an adult head) and indicate that it is suitable for teenagers and adults with small heads (laughs). It's uncomfortable on my face, more like cutting the bridge of my nose during rehab, but until I find another one, what choice do I have?
