IST dive equipment has been a trusted name in scuba and watersports gear for over 35 years. Safety, reliability and quality are our primary design objectives when bringing any new product to our customers, and our IST Synthesis 2 Window Aluminum Frame Scuba Dive Snorkeling Mask is no exception. The Synthesis uses the same lightweight and robust 6000 series aluminum as the Panorama to give the mask strength without added weight. CNC and plastic injection construction methods make for a stout and supportive skirt. The flexible buckles are attached directly to the skirt so they do not interfere with fitting, enabling the mask to be folded flat for compact storage as well: a feature appreciated by sport divers and technical divers alike. Buckles auto-adjust to the diver’s preferred strap angle. An option for tinted, color-correcting lenses bring the underwater world to vivid life and reduce surface glare. A sturdy mask that’s ideal for use as rental equipment.
