The Hathor spearfishing and freediving mask is designed to offer a low volume inside, facilitating the equalization phase and ensuring a profile that does not interfere with the field of vision. It is made of hypoallergenic silicone co-molded onto a nylon frame, and the tempered glass lenses are co-molded directly into the supporting frame for greater strength and less bulk. The low volume inside facilitates the equalization phase; the profile that adheres to the face has dimensions calculated not to interfere with the visual space. The strap adjustment is intuitive and ergonomic, fitting to the head without putting pressure on the ears. With a wide lateral field of view, this mask ensures optimal visibility during use.
