Photochromatic lens and advertising (which suckered me in to buy this piece of junk).
Weaknesses:
Fogs up very badly. I had a 32 degree head case and that worked even better than this high price, crappy mask. Very uncomfortable around the ears. Learn from me and avoid at all costs (literally). Just buy a JT mask.
Conclusion:
- Vision is alright, but fogs like a MF.
- Very uncomfortable around the ears.
- Definitely not worth the cost....should be around $20.
- Would not recommend to anyone. Mask totally blows.
