so iv'e gone through a fair share of dive masks and i cant find one that fits my face. they all leak a bit more then id like... so i decided to just buy the coolest low volume mask i could find. it leaked worse then anything else i had, but i liked the look. i put silicone where it was leaking near the nose and when it was half way cured i molded it to my face. went for a dive the next day and it was a whole new mask. do rough up the mask so the silicone it sticks well.
