I've been using this mask for around 2 years or more. I love it. I've had no problems with it at all so far. It's comfortable, I've had no fogging, and it looks pretty cool. Unfortunately I couldn't convince my friends to get it because they think "the more price, the better perormance"...wrong.
JT has some great masks. This has never failed me. If your looking for a new mask look no further.
