IST Proteus Twin Lens Mask

IST’s newest mask, which uses varied-thickness construction to provide a secure yet forgiving fit, offers a wide field of vision, low internal volume and the ability to accommodate a range of facial profiles.


  • The Proteus now has a larger field of vision
  • Despite the increase, the internal volume remains small because the lenses are brought closer to the eyes.
  • The strap buckles are attached directly to the skirt (not the frame, unlike some designs) so they will not interfere with fitting, especially when it comes to people with wider facial profile.
  • Soft, hypoallergenic skirt will not yield due to increased pressure
  • Pronounced nose pocket easy to access with gloves


Colors: Clear Blue, Black Silicone/Black, White, Red, Green Silicone/Green

I am a rookie at snorkeling. I have been twice and enjoyed. I have a narrow face. I will be using a snorkel mainly on vacation a few times a year. Do you recommend this mask, IST Proteus? I was thinking about a dry snorkel. What snorkel do you recommend?

Hello and thank you for your inquiry. I've spoken with IST and they recommended the IST Green Silicone Bluetech Low Volumn Twin Lens APNEA Mask for a narrower face. As far as a dry snorkel goes, the IST 3D Flex Dry Snorkel is a best seller. You can place your order at and let us know if you have any questions. Happy Snorkeling!
