Very good thermal lense. Haven't had it fog once
Excellent peripheral vision
The flexible bottom half will usually cause balls to roll of rather than break.
I dont know if they still do this, but mine came with a clear and a mirror lense.
Comes with a bag
Not much. The foam pieces that sit behind your ear have a habit of falling off. The price is a little high, but thats true of any good thermal system. The only other thing is the flexible bottom half will become mishapen if you store it wrong.
Definitely the best goggle system I have used. I would and do recommend it to anyone.
