Because let's face it, between checking dive computers or holding dive lights, you've already got your hands full. Works with ALL GoPro Models! The OCTOMASK features safety tempered lens, and a low volume design that helps keep the mask close to the face for great visibility, while the super-soft silicone helps ensure a great seal. This mask fits nearly everyone!
