- Better face fit: The new mask design is optimized for a comfortable seal on the face, with two elastic straps at the back to keep the mask securely in place. - Clear, fog-free airflow: Separate inhalation and exhalation channels provide high-capacity airflow, delivering 20-50% more air than standard masks, reducing air mixing and fogging and minimizing odor buildup for easier underwater exploration. - Wider, sharper underwater view: The facepiece is designed for an expanded field of view and uses a translucent material that reduces light refraction, giving a more direct and clearer view of underwater life. - Safe, comfortable materials and fit: Made from PC and medical-grade liquid silicone, odorless, safe and non-toxic to prevent facial discomfort, with a 3D-fit for your face and an adjustable strap for easy wearing. - Practical use scenarios: ideal for recreational snorkeling in reefs or open water, pool practice for beginners, and observing marine life or photographing underwater scenes.
