IST Pegasus Full Face Rubber Dive Mask

Sometimes, it is the simplest equipment that survives the test of time.

The Pegasus M37 is certainly representative of that concept. This is a serious hardworking mask that’s only available in serious hardworking Black Silicone and Black Rubber. IST has built a reputation that began over 35 years ago with constructing quality masks and snorkels. The Pegasus M37 Full Face Scuba Diving Mask is at the bedrock of that foundation, a mask so solid, it is still most commonly used for commercial diving purposes. The retro M37 is itself almost symbolic of IST’s standing as a long-time supplier of quality, reliable and cost-effective diving products.

Pegasus full-face is a bullet-proof full-strength mask that is capable of protecting divers from extreme cold or grimy, polluted water. The 3-end strap secures the mask evenly creating a positive seal, combined with a soft double feathered edge skirt for a perfect seal every time. Pegasus will give you no jaw fatigue because you don’t have to bite on to the mouthpiece. A wide field of view tempered glass safety lenses will give you great underwater vision.


  • The convenience of demand air, with the comfort of not having to bite the mouthpiece
  • Eliminates jaw fatigue and/or denture slippage
  • Multi-strap adjustment and easy, nose access for equalization
  • Allows for the attachment of most types of regulators
  • Comfort-fitting
  • Adjustable fits all adults
  • Silicone skirt and strap with low volume
  • Tempered glass lenses
  • Maximum vision

At its heart a simple scuba mask
You take the upper portion and it is a very typical scuba mask, you extend it down in the most simple and direct way, but apparently it looks BDSM and you get made fun of on reddit and try to resell it on ebay to buy the OTS Spectrum 
If you dont care what people think, you may find this mask will and proficiently do all that you need it to do, and hope that looks more like a gas mask than the latter

Hey, just wanted to be sure I understand correctly, you offer this mask in Rubber and another version like it in Silicone? I am replacing my old Cressi Sub FF mask which was rubber and wanted to stick with what I was familiar with. BTW, What happened to the Cressi Sub model of this mask, I have owned two over the past and now can't find one. Did IST buy out the Cressi design? Love the simplicity and comfort of that old Cressi mask. Thanks Paul
