The A1 has been designed with an attractive style, boasting high performance for scuba diving and freediving. It features a single-lens made of tempered glass lens having special treatment that makes it completely anti-fog, an excellent feature for any dive. The lenses are inclined and have an inverted teardrop shape, increasing downward visibility. This allows better control of the scuba diving equipment. The skirt and strap are made of soft silicone, ensuring a high-adaptation fit for most face shapes. The top of the internal skirt features a double edge that drastically increases 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, elastic flap, providing not only a flexible fit but also reducing drag and the risk of breakage. 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 yellow lens increases the contrast, making objects more visible. Moreover, it increases the vibrancy of the colors underwater.
