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

The design is built to cut drag. The minimalist shape, low-profile lenses and reshaped ergonomic buckles all 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 where you want it and put the mask on quickly. Light, slim and purpose-built, the X-Tream is for breath-hold divers who want every advantage in the water.
