Soft rubber areas for bouncing
Visor a little dificult to attach, but no big deal
I was sceptical at first about this mask because it was coming with my X7 package, and because of some of the reviews found here. Once I got it and used it, I was sold. There is no sweaty foam to contend with because the mask uses a soft silicone-based rubber to hold itself to your face. The rubber is soft, don't know about the compliants others had about it being hard plastic and such. It has not fogged up yet, even in the woods on a humid day thanks to the anti-fog lens and the seal made by the silicone. The lens is easy to take off and on -- unsnap the strap, slide out the clips.
Overall, I could not have gotten a better mask for the money (approx. $25-$35). This is an excellent mask, and I recommend you give this one a shot.
