Thermal lens, flex mask, great ear protection, field of vision
Could protect a little more of neck, which would allow for more bounces
Great low profile mask. The thermal lens does not fog up and has great field of vision. There is great coverage around the ears but the mask has soft ears so it may hurt a bit to get shot there. I'll update when I get shot there. Your neck is really exposed but your provided with the same coverage as any other low profile mask. The flex part works really well, I had two balls bounce off the mask.
Nothing is perfect but this is by far the best mask on the market. I would highly suggest it. The flex part will definitely save you a few times. I thought it preformed better than the i3 and is cheaper.
