AFTER SALES SERVICE - As long as you are our customer, from the day you purchase the full face snorkel mask, we provide 24-hour support. We are committed to delivering a satisfying buying experience. 180 DEGREE PANORAMIC VIEW - Unlike traditional snorkel masks, the full face design allows comfortable breathing through both mouth and nose. The flat large lens reduces underwater distortion for enhanced visibility. FREE BREATHING DRY TOP SYSTEM - Features three separate air channels to maximize airflow, help prevent fogging, block salt water from entering the mouth, and reduce the risk of gagging. ANTI-FOG & ANTI-LEAK - Designed with a hypoallergenic silicone skirt that creates a secure, leak-free seal around the face. The separate breathing chamber isolates exhaled air from the nose and mouth, reducing condensation on the lens surface. ENHANCED FEATURES - Includes a foldable snorkel tube for convenient packing and improved stability to prevent detachment. A removable camera mount allows you to attach a camera and record underwater experiences. This snorkel mask includes all the features todays swimmers need to enjoy snorkeling. PREPARATION: Ensure there is no sand on the mask or tube. If present, rinse the breathing tube and mask with water. Once clean, the mask is ready for use. CHECKING THE SEAL: Place the mask straps over your head and check the fit on your face. Breathe normally to check for leaks. If you feel slight pressure changes while breathing, the seal is secure. If not, adjust the strap size accordingly. USING THE MASK: Once in the water, swim on the surface and breathe calmly through your mouth or nose. If you feel lightheaded, remove the mask immediately. Keeping your chin slightly raised will optimize breathing. If you experience breathing resistance, it may be due to temporary water coverage on the snorkel. The dry top design helps prevent water entry from the top of the snorkel. If water enters the mask, lift your head above waterthe water will drain through the chin valve without needing to remove the mask. WHY CHOOSE THIS PRODUCT: The foldable snorkeling mask addresses common issues with non-foldable models, such as difficulty in installation, risk of the breathing tube detaching during use, and the need to frequently replace O-ring seals. This model offers easy installation, secure tube attachment, requires no accessory replacements, and is designed for extended durability.
