Product Description

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 that it is still 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. 

This full-strength mask is capable of protecting divers from extreme cold or grimy, polluted water. The 3-end strap combined with a soft, double-feathered edge skirt secures the mask evenly, creating a positive and perfect seal every time. The Pegasus prevents jaw fatigue since you don’t have to bite on the mouthpiece. The tempered glass safety lenses will give you great underwater vision and field-of-view.

  1. Do not waste your time with this mask

    Posted by Nathan on November 9th, 2020

    I am a professional scuba diver that specializes in in-water boat hull scrubbing. I have been plagued with getting the remnants of my cleaning job on my face and to say that it is annoying is a mild understatement. I have long wanted a full face mask to help keep the junk out of my face and to ease my jaw fatigue that results from hours spent in the water with a regulator and snorkel everyday. I have eyed other manufacturers models but my pockets don't run that deep. My divemaster instructor is an IST distributor and suggested that I give this model a try. The price seems right and the design seemed adequate so I ordered one. Well I received the mask and set it up with my regulator and I could not wait to try it out. Also, I prepped the glass properly and applied anti-fog chemicals. Today was my first day with the mask and to say that I was disappointed in an understatement!! The field of vision is horrible. As a professional diver I need a large field of vision that this mask does not even come close to providing. There was a huge issue with fogging that I could not seem to overcome. The overall size of the mask does not fit well and despite experimenting with the straps I could not keep water from seeping in. The mask felt like it was going to pop off at any time causing a great deal of anxiety. I am very unhappy and disappointed with my purchase and will not recommend it to anyone that I know...
