Frameless Style

The IST MP110 is a premium-quality frameless mask that provides exceptional performance in one simple, lightweight design. Instead of a structured frame, the mask features a shatterproof tempered glass lens sealed with a dual-edge layer that keeps water out and minimizes bulk.

Comfortable & Lightweight

The ultra-flexible construction eliminates unnecessary weight that can add drag and slow you down. Sleek liquid silicone is extremely soft and supple, forming to your face for a tight seal that won’t irritate your skin. The material is even hypoallergenic, so divers with sensitive skin won’t chafe or break out.

Easy to Pack

The malleable silicone, shatterproof lens and adjustable buckles that attach to the skirt allow the mask to fold up flat for easy packing. With minimal weight and reduced volume, you can safely slide it into any backpack, carry-on or suitcase without it being damaged.

Varied-thickness construction. Hypoallergenic skirt is soft yet it will not yield due to increased pressure and depth. The nose pocket is easily accessible irrespective of the thickness of the gloves used. The MP201 has a larger field of vision compared to its cousin the Bluetech (M88). Despite the increase, the internal volume remains small because the lenses are brought closer to the eyes. The strap buckles are attached directly to the skirt (not the frame, unlike some designs) so they will not interfere with fitting, especially when it comes to people with wider facial profile.

IST dive equipment has been a trusted name in scuba and watersports gear for over 35 years, and a pioneering innovator in supplying diving masks with prescription lenses. The IST Corona Twin Lens Scuba Diving Snorkeling Mask with RX Lens Option just may be the most popular mask in our vast lineup – and not only because it’s an attractively priced, prescription lens-available mask.

The Corona’s high-end lenses are made from super-transparent, tempered glass to offer stunning panoramic underwater viewing, scratch-resistance and maximum safety.

Durable polycarbonate frame holds twin windows for quick clearing of trapped water and maximum field of vision. Swivel buckles allow the diver to adjust the mask to the most desirable position for a perfect, comfortable fit.

Available black silicone skirt option blocks light from reflecting off the lens in bright water conditions, while the clear skirt option allows maximum light entry in dim water conditions.

A sturdy mask that’s ideal for use as rental equipment.

Oversized lens design significantly increases field of vision horizontally and as well as vertically. The internal volume, however, is not increased noticeably as the lens is brought closer to the eyes as much as possible.
