Questions and Answers for IST Full Face Mask - Rubber:

  • Mary:

    Would this mask work for a snorkeler? Please be specific. My husband can not find a mask that doesnt leak, because of grooves in his face.

    Bill  (Certified Scuba Instructor at

    Although this will work with a snorkel it is not designed for that and may be a little cumbersome.

  • ray:

    where can i find replacement lens for the m37-r

    Darrick  (Certified Scuba Instructor at

    Hello Ray, you would need to contact the manufacture directly. Since the lens are built directly into the mask they would be the only ones who can replace the lens in the mask. You can contact them directly at (909) 622-9600.

  • Bobbi:

    Im unable to scuba dive because Ive had issues trying to use the traditional mouth regulator for breathing. Do those somehow attach to this mask or does it require a special regulator? Asking because for vacations where we rent gear it would be ideal to only have to take along the mask so that I could enjoy diving with my husband...

    Bob  (Certified Scuba Instructor at

    This mask is designed for use with the regulator of your choosing. Very few resorts or dive shops are going to attach their regulator to your full face mask. On a safety note, while this will allow you to dive without the regulator mouthpiece in your mouth, it is still HIGHLY recommended the user be able to dive with a traditional regulator mouthpiece. In the event of an Out Of Air Emergency where you''d have to use another diver''s safe second, if you are unable to breath from a normal second stage you''d be placing yourself and your buddy in severe danger.

  • DARCY:

    can I use this mask for snorkeling? can I attach my mouthpiece from my snorkeling gear to it? have tried snorkeling but keep gagging with piece in my mouth. Thanks

    Bob  (Certified Scuba Instructor at

    I have heard of people using it for snorkeling. Pretty much any snorkel with a replaceable mouthpiece will fit it.

  • Deb:

    Does the mask seal and act just like a regular half mask? Can you dive to recreation diving depths of 130 feet? How do you clear this mask?

    Darrick  (Certified Scuba Instructor at

    Hello Deb, think of this mask as your mouthpiece of your regulator. If you got this mask you would be able to pinch your nose to clear but since this mask would replace your mouthpiece you would be able to breath threw your nose while wearing this mask.



Pegasus full-face mask protects divers from extreme cold or grimy water. The 3-end strap secures the mask evenly and helps creating positive seal. Available in black silicone or rubber
