My visor came a bit deformed; required some bending and prying. It's new, I should be the first to wreck it.
Why choose the Flex 7 over the Flex 7 IZE? Personally, I prefer the thicker mouth and chin protector of the Flex 7 over the thinner rubber on the IZE. As much as I love my battle marks, I prefer they not be on my neck or face. I recommend this mask to EVERYONE!
