• The IST M37 Pegasus mask is the ideal choice for commercial scuba diving
• Slim, low-volume design provides the convenience of a full-face mask without weighing you down or adding unnecessary bulk
• Eliminate jaw fatigue by securing your octo to the mask's mouth opening - allowing you to focus on your dive instead of keeping your gear in place
• The dual-lens window mask is crystal clear and made of tempered glass for maximum durability and resistance to impact, while the large lenses provide a panoramic view with minimal eyesight obstruction
