Doesn't really matter here, does it?
My mask is an olive Spectra (thermal) with woodland goggle skinz and x-wind fan
Strengths:
When your mask starts to fog, which is rare with my spectra thermal, you just switch on the fan, and just like that the mask is fog free.
Weaknesses:
Surprisingly hard to install & a bit loud.
Conclusion:
An overall good product, good price, (the $80 is wrong on this site. got mine for $25.), but if you have thermal lesnses, it is probably not a necessity. If u got the extra cash, go for it.
