I have bought a number of different brand masks, and I can honestly say I LOVE(!!) my Profound masks the best! They are just the right weight, I feel well protected and yet can be heard), and the fit is like they (yes, I bought two) were custom made for me. I appreciate the filter pocket, and the adjustable ear straps are very comfortable, even for my all-day use. Can't wait for more fabric choices, but in the meantime I am delighted with mine and sure they'll last a good long time...very quali...
