The entire mask (excluding the lense) is flexable. I have had balls bounce of the face and ears. It has a low profile.
-The foam on the face isn't very sturdy.
-it is too close to my face so my breath condences on the in mask and on the lense so the thermal isn't completely effictive.
-I detect a hint of lense distortion.
It's an alright mask, but for half the you could get a V-force Shield. A much better mask.
