Omer Alien low volume mask is designed with spearos in mind to be as hydrodynamic as possible. Omer Alien dive mask is positively the first mask on the market designed and conceived exclusively for spearfishing. The buckles have been positioned on the silicone skirt, instead of the classic position on the mask frame. This allows for greater hydrodynamics and reduces the total weight of the dive mask. The lenses sit close to the eyes for a wide field of vision. The Omer Alien mask is great for spearfishing, freediving, scuba diving or just snorkeling.
