Mask designed and developed as a support tool for spearfishing and deep apnea. The internal volume of 110 cm3 makes it one of the smallest masks on the market. This reduces the waste of air used to compensate for it. With the use of pure 60 shore silicone it was possible to obtain great comfort. The nose pad features a rough texture which is meant to improve its grip when offsetting. To obtain a good field of vision despite the small size of the mask, we worked on the distance of the lenses from the face and on their geometry. The strap is adjustable using the two clips on the side of the mask. The strap is made of a more rigid silicone to increase its duration and to ensure that the mask always remains adherent to the face, even at the end of the ascent when the surfacing speed increases.
