Dry Snorkel with Drain Valve：This advanced dry snorkle set has a top-mounted automatic valve that blocks water entry. The valve closes instantly when submerged and reopens on surfacing. A splash guard keeps water out even if waves wash over your head. Unlike jam-prone float-type valves, our valve resists clogging from sand and debris. Plus, the bottom one-way drain valve enables fast water discharge. Liquid Silicone Skirt: The skirt of the diving mask is crafted from food-grade liquid silicone, which is soft, comfortable and fits facial contours perfectly. Its double-layer waterproof design eliminates concerns about water leakage and facial pressure. Besides, the mouthpiece made of the same soft liquid silicone ensures extra comfort in your mouth. Adjustable snorkeling Mask Strap: The mask strap is made of soft silicone material, and the adjustable buckles on both sides allow for easy length adjustment. Combined with the 3D mask design, it fits different face shapes and groups of people. HD Panoramic View: The lens is made of tempered glass, featuring shatterproof and scratch-resistant safety performance. Combined with a 180° panoramic field of view, this snorkeling gear for adults delivers an immersive underwater experience. Two-in-One snorkel mask set adult: This set includes a snorkel mask, a dry snorkel, and comes with a storage bag as a gift.
