Mares Bonito X-One Mask, Snorkel & Fin Set
Mares Bonito X-One Mask, Snorkel & Fin Set
The Dive360 Take
The Bonito X-One is a practical starting point for snorkelling holidays. You get a mask, snorkel and a pair of short adjustable fins in one set, with a compact blade format that is easier to pack than a long diving fin.
The X-One heel straps use a buckle-free adjustment system, while the snorkel’s splash top and purge valve add useful help at the surface. Choose the set by fin size, then check the mask seal and mouthpiece comfort independently—three pieces of gear still means three things that need to fit.
