The Seac One is a mask that has been designed for scuba diving, but is equally at home when being used for Snorkelling, Free Diving and Spearfishing. It has two symmetrical tempered glass lenses, polycarbonate structure and an anatomical skirt made of hypollergenic liquid silicone. The strap is easy to adjust thanks to the "Easy Touch" buckle with release button.
The Seac One Mask also benefits from being able to take optical lenses (please enquire for details).
