Take Bob's word on this mask. THIS IS GREAT. I have used this face mask every time I've played for a good long time and it hasn't let me down. It was my first face mask and is still my only. I've been lit up in the face more time than I care to remember and it hasn't failed me yet. The thermal is just a dream. It can put up with the most ridiculous conditions you can imagine. The only time it has ever fogged was I played a morning game in a swamp (yes, a swamp) when it was 90 degrees and raining off and on all that day and the day before. And even then, the fogging wasn't too bad. That weather fogged up Revison Desert Locust googles, a Dye-i3, a Dye-i4 and Boogie Regulators. Not to mension they are also extremely comfortable. This is the single best thing since sliced bread. Or Thunder B's.
