When I first wrote this review, there was no category for the Nuvis-1, so now I am putting the review in the proper section.
This mask has THE most advanced lens on the market today - period. The photochromatic lens is the most stunning feature. Its uncanny ability to react to UV and sunlight intensity and give corresponding tint is remarkable. This will save you an unbelievable amount of hassle and trouble when conditions change. The most intense feature about this mask is most notable on days when you have clouds and sun alternating sky time. I cannot say enough great things about the photochromatic lens! IT RULES OUTRIGHT! This is especiall important for tournament players who can get glare on hyperball and sup air fields.
mine was missing a little piece of stabilizing foam. no biggy. the hole in the visor for the fan switch wasn't punched out so i had to make the hole. lastly, the bottom is really flimsy. i haven't been shot in the mask yet, but i assume it'd hurt to get hit in the mouth. oh yeah, if you for some reason stick your tongue out while wearing this mask, it tastes really bad.
If you live in one of the aforementioned areas, make sure you have a thermal as a back up so your day is not ruined by foul weather. Use this mask when the humidity is low and moisture is not locked in the air by things such as tree canopy's. If the day is not that humid, and you are playing in open areas (ie. Speedball, or open woods games), THERE IS NOT A BETTER MASK ON THE MARKET. Conclusion, the Raven Nuvis-1 is the best mask in the world, provided the conditions are not too abhorent. However, because of this lack of versatility, it simply does not rate the top spot. Its performance is so outstanding when conditions are right that I am tempted to give it a 10, but since it is a "conditions specific" mask, then I have to deduct two points.
