So far they work very well on aircraft carriers. It takes a lot of use before needing a wash, and dissipates the heat of the F/A-18 Super Hornet engines so well I could almost walk straight through the Jet Blast if it wasn't also trying to knock me over. . I haven't had a chance to test its Cockpit FR capabilities yet (hopefully I never will) but once I do I'll update this review with the results. I now have four of these face masks and am very happy with my purchase. Thank you Benchmark!
