The Mares X-Tream is an ultra-low-volume mask engineered for serious spearfishing and freediving. Reducing internal volume to the minimum cuts down the air you need to equalise the mask on the way down, which directly saves breath on deep, repetitive dives.

Everything about the design is built to cut drag. The minimalist shape, low-profile lenses and redesigned ergonomic buckles all work to reduce the mask's hydrodynamic footprint, while the close lens-to-eye distance keeps the field of view generous.

It ships with a very low-profile, hydrodynamic strap and an integrated snorkel stop, so you can clip your snorkel exactly where you want it and don it quickly. Light, slim and purpose-built, the X-Tream is for breath-hold divers who want every advantage in the water.
