Review:
The Vents Helix are a great pair of goggles.
They give full coverage of your face and ears.
They have a perfect field of vision - you don' t lose any peripheral sight.
The thermal lens performs flawlessly.
The lens is extremely easy to change. You just flip a couple of knobs at the temple and pop the lens off.
They are lightweight.
The head strap grips well.
They are really cheap - less than $35.
I got mine in olive, which is good for woods ball. My only complaint is that I wish they came in camoflage.
Conclusion:
Don't get suckered into buying an expensive mask. The Vents Helix look wicked cool, they're cheap, and they perform as well as anything on the market.
