Limited protection around the lower jaw and through
I tried on the i4 at my local proshop and got my own right away. It's hugs your face so close and your vision is amazing compared to the old i3 . It's got great looks and feel and is priced right, at around 100$ you get what you pay for. It's got a bunch of different lenses you can swap out even a hi deff lens. The only thing I dislike a little is the lack of protection around the jaw line, altho that's why it fits so nice. All in all I won't be needing a new mask for quite a while
Great mask great buy great vision great looks. Could be a little longer to cover your jaw fully
