New Safety Breathing Mechanism Snorkel Mask: The Keystand dry top snorkel mask full-face uses a less complex technology that you’ll be inhaling through the top tube and exhaling through two valves at the side-bottom. And the Anti-fog flat crystal lens, enough breathing space and coating for a pristine ocean experience, that allow you get to enjoy the more crystal-clear views than other masks, with less distortion and HD180-degree panoramic views.
25% Lighter than Other Diving Gear: The portable snorkel mask perfect for frequent travelers and backpackers! With the detachable tube, attachments and materials. There’s no compromise on quality or features - just less weight for you to carry around. The updated exhalation valve on both sides can meet long-term snorkeling without dizziness and hypoxia symptoms. Easy to take off and put on, you can remove the mask quickly and easily in emergency. Please Note: Do never snorkel alone.
