The SERENE UP-1521QB adult travel set comes with an M-16 Serene mask, a USP-250 snorkel, and a pair of UF-21 fins. The UM-16 Serene mask gently conforms to the contours of your face. Constructed with pure silicone, the Serene has been crafted for divers who want a wide field of view combined with a low volume design. The USP-250 dry snorkel features TUSA Hyperdry Elite dry top technology (pat p) that stops water from entering into the snorkel, a drain chamber and purge valve for easy clearing, and silicone mouthpiece. The UF-21 fins have an advanced multi-flex long blade design, thrust channel technology for superior propulsion and the foot pocket is made with a soft, durable compound designed for comfort. The open-heel design allows for quick and easy size adjustment and the silicone heel strap enhances comfort and durability. This fin is engineered to provide a lot of power for its compact size. The fins are lightweight and ideal for travel. Comes standard with travel bag.
