The field of vision is excellent, and with the Thermal lens, you'll get the least amount of fogging possible. Comfortable fit and great protection to all areas.
Breathing is absolutely horrendous in this thing. Several of my friends, also with Spectras, have told me of the same thing. On a warm day, the inside of the mask is a sauna, and it makes you want to take it off just to breathe clearly.
Aside from the breathability issues, it's a good mask and a good price (you can find them around $40 or so). If you're looking for something a bit better, the Flex 7 is a better system. The holes are arranged differently and it's just less stuffy to breathe. Spend the extra $15 - $20.
