The A1 has been designed with an attractive style, it boasting high performance for scuba diving and freediving. It features a single-lens made of tempered glass with a special sun ray protection, preventing the damage of the eyes. The lenses are inclined and they have an inverted teardrop shape, increasing the downwards visibility. This allows better control of the scuba diving equipment. The skirt and the strap are made of a soft silicone ensuring a high-adaptation fitting most of the different face shapes. The top of the internal skirt features a double edge that increases drastically the sealing. The drain skirt design improves water expulsion during mask clearance and minimizes water pooling. The buckles are connected to the frame with a soft and elastic flap, not only for a flexible fit but also to reduce drag and the risk of break. The buckles allow an immediate adjustment of the strap length with one hand, even while wearing gloves. It features a soft nose pocket for ease of equalization. The UV420 lens blocks harmful HEV which causes oxidative stress and deterioration of lutein. The lutein is a pigment in the retina that acts like natural sunglasses but can be damaged if it absorbs harmful lights. The yellow lens increases the contrast making more visible the objects. Moreover, it increases the vibrancy of the colors underwater.
