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 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 visual clarity. 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 - Offers superior comfort with a hypoallergenic silicone skirt that creates a secure, leak-free seal around the face. The internal breathing chamber separates exhaled air from the nose and mouth, reducing condensation on the lens surface. ENHANCED FUNCTIONS - Includes a foldable snorkel tube for compact storage and improved convenience. A removable camera mount allows attachment of a camera to record underwater experiences. This snorkel mask includes features designed for a comfortable and enjoyable snorkeling experience. Preparation: Ensure no sand is present on the mask or tube. If sand is 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 when breathing, the seal is secure. If not, adjust the strap tension. Using: 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 can improve breathing performance. If breathing resistance occurs, 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: This foldable snorkel mask is designed to address common issues with non-foldable models, such as difficulty in assembly, risk of the breathing tube detaching during use, and the need for frequent replacement of O-ring seals. This model is easy to assemble, features a secure breathing tube that stays in place, requires no accessory replacements, and is built for extended durability.
