Single-use vent valve at the bottom of a pear-shaped chamber provides easy water drainage and helps keep the unit dry. The valve is offset from the mouthpiece tube for easy cleaning, and water can be expelled even underwater by a strong exhale. Easy mounting to standard snorkel/mask: The snorkel attaches to standard snorkel or mask systems. The adjustable clip with quick-release clips onto a mask and can be moved up or down along the snorkel tube for a comfortable position. This attachment method reduces hair tangling between mask and snorkel. Oval upper tube for more air and easier breathing: A large-diameter tube allows full breaths without struggle. The curved upper tube sits close to the head to minimize mouth pull, making it suitable for snorkeling, sport diving, swimming, and more. Mouthpiece made of food-grade liquid silicone: Very soft and safe for the mouth, providing a comfortable seal. The angled and ribbed mouthpiece design supports longer use. The silicone mouthpiece is removable and replaceable. Use scenarios: - Snorkeling in open water or reef areas for easy, comfortable breathing and quick water release. - Pool training or lap swimming for efficient breathing and reduced mouth fatigue. - Light scuba or adventure diving with a mask, offering secure attachment and a comfortable, hair-friendly setup.
