The foam lining around the lenses is a hard foam, unlike my Smith MX goggles, and I don't believe it would filter dust well, or wick away sweat. I bought these to use while riding four wheelers without a helmet, needing something to protect my eyes and keep dirt out, and although I haven't tried yet, I don't believe they would keep out the dirt for my intended purpose. They also will not fit with a shoei vfx-w MX helmet, not to say I expected them to. Maybe they have superior protection against fogging up as you are not always moving in a tactical situation, but I won't use them for riding my quad and overall was not impressed.
Pros: High impact, interchangeable lenses
Cons: Foam lining around lenses
