The Rob Allen Cubera Clear Lens Diving Mask is a low-volume dual-lens mask suitable for spearfishing, freediving and snorkelling. Its low-volume construction reduces the air space inside the mask, which makes equalisation easier at depth. The mask has clear tempered glass lenses and a soft black silicone skirt, and its integrated strap system allows quick adjustments for a secure seal on the face.

How to use and care
Wet the skirt, place the mask on your face without the strap, inhale gently through the nose and check that it holds a seal, then adjust the strap so it is snug but not tight. A new mask can fog at first; use a mask de-fog spray or solution before diving rather than burning the lens. Rinse the mask with fresh water after each dive and store it in a case away from direct heat.
FAQ
Why does my new mask fog?
It is normal for new dive masks to fog. Use a de-fog spray or solution before diving and the fogging will lessen over time.
Is it good for freediving?
Yes, the low-volume design reduces the air space inside the mask, which makes equalisation easier at depth.
Will it fit a narrow face?
Fit varies between faces. Test it by pressing it on without the strap and inhaling; if you have a small or narrow face, contact us for advice.
