Often scoring top marks on our customer feedback and great value, the IST Corona M55 diving mask is a great entry level mask for casual snorkelling and diving.

It has been one of the most popular IST diving masks (this version with prescription lenses) and its superior fitting and comfort are the reasons behind the success. Its swivel buckle allows the diver to adjust the mask to the most desirable position. The low internal volume gives unrestricted view.

    Fantastic product

    Absolutely brilliant. Had a slight leak the first time I used them, but adjusted the strap and no leaks. It’s so nice to be able to see everything again when snorkelling. I would definitely recommend this mask. It’s brought me a new lease of life for my favourite holiday pastime.

    Great mask fits my lens prescription

    Used for the past week and it has been great. The prescription lenses make a world of difference.

    Thankyou!

    Second time Snorkeller!

    We were visiting the Maldives and snorkelling was high on the list of things we could do. Alas I’m short sighted but after a quick phone call to get the correct prescription my mask enabled me to see comfortably ocean life. They also came in a great carry case. Amazing, thank you
