Looks (to some)
Weight
Bounce factor
The custom factor
Weaknesses:
Lack of upper neck (right below the ear) protection.
Other than that, perfect.
Review:
I own 4 proflexes
A flex 8
An elite flex
A proteus
And some other lower end masks for friends.
There's a reason I own 4 proflexes though... They are simply amazing. I wore them yesterday for a big game, and I forgot I was wearing them.
I have diff. Masks for diff. Places I play at (so diff. Lense styles, diff. Colors, etc) so I always match and always have the right lense for the place I'm playing.
If its sunny, I have the mirror lense
Dark, amber lense
normal, clear lense
And another clear lense.
These can be had for around $40 brand new if you look... And custom soft ears are even cooler... PM me for details on those.
Conclusion:
Want a great mask at an even better price? Grab a proflex.
