Very well-made. Low-profile mask (fits close to your face). Excellent sealing around your eyes, and the strap holds it tight to your head. Tough plastic upper portion combined with a flexible lower jaw portion. Available in a variety of colors. Peripheral vision is excellent. Thermal lens is almost impossible to fog.
A little pricey, but I am becoming a firm believer in NOT skimping when it comes to protecting your face and eyes. I haven't had to remove the lens yet, but it doesn't look like it will be easy. When watching cartoons or the 3 Stooges you pick up annoying reflections from the dual pane lens :)! I wish it would have more throat/neck coverage.
This is the second mask I have owned and it will take a lot of convincing to make me believe there is a better mask out there. This mask did not fog on me at all, and I've had problems before. I really like the improvement in your peripheral vision; some masks restrict you to about 70 degrees of vision when you look straight ahead, this mask gives you almost 180 degrees. Final comment: I KNOW my eyes and face will be protected when I wear this, and I will be buying another as a backup in the unlikely event the one I have fails, or to lend to others if they need it.
