There is no similar product compared to this. In my opinion this is the best mask of 2007 ever. If i had to pick a similar mask my pick would be the proto switch axis.
the marker i use with this mask is a proto 07 , pulse hopper, and a 4500 psi hp tank.
Has great lenses it also has a great cooling system for your ears.
It is hard to take out the lense.
My full review is this gun is good looking with any item it is the best mask is veryu light weight if you think this mask is heavy you must not have a muscle bigger than a twig. It is a little expensive not much though. so buy this mask.
Very good mask and it is a little expensive but not that much dont buy it if you dont have tournament experince though.
