Although dye can be an expensive brand, i'll give them this one, there i4's are pretty nice. There venterlation and they are compact and tight to your face. However if you want a less tight mask which is slightly cheaper go for grillz, I have heard good things about them. Personally I have E vents and I don't like them that much, but thats from my poor experience.
Hope this helps a little
