The Optik Comfort mask strap, with an integrated snorkel keeper, offers a highly convenient and tangle-free solution in your personal colour preference. It is compatible with the Oceanpro Optik and Portsea masks, as well as any other mask that has a universal female buckle. The quick-release buckle functionality makes it easy to clip on and off, and the easy slide adjustment strap accommodates multiple head sizes and can be used with or without a hood. Customise your mask to match your dive kit.
