FULL FACE FOR EASY BREATHING - Our full face snorkel mask set features 3 completely separate air channels (mid air intake, air outlets on both sides) that can be sucked through the upper tube and exhausted through the two valves at the bottom of the side. (180° Panoramic View) Our snorkeling mask uses a clear anti-fog flat crystal lens that eliminates eye glare and discomfort in the water. 180º panoramic view allows you to see the world of the sea. With the added detachable motion camera bracket, you can easily capture your adventures, and you can record the wonderful underwater world and share with your friends and family. (Anti-fog Design & Prevent Water Intrusion) The snorkel mask comes with high quality silicone, and the soft and suitable silicone layer is completely wrapped to achieve a leak-proof effect. Independent inhalation and discharge channels prevent snorkel masks from fogging and anti-fog coating provides clear vision. (Easy to operate & Portable) The full-face snorkeling mask is 25% lighter than other diving gear. It is perfect for frequent travelers and backpackers! Updated exhalation valves on both sides allow for long term snorkeling without dizziness or low oxygen symptoms. Easy to remove and put on, quick and easy to remove mask in case of emergency. Note: Do not snorkel alone.
