The VISIO TRI-EX adult combo includes the UM-31 Visio Tri-Ex mask and the USP-250 Snorkel. The UM-31 Visio Tri-Ex mask is a revolutionary 3-window design that offers an ultra-wide 168° panoramic view. This amazingly wide viewing angle is achieved by the incorporation of domed side windows and the significant reduction of frame structure around the lenses, increasing the field of vision dramatically over traditional masks. The UM-31 mask gently conforms to the contours of your face. Constructed with Pure Silicone, this mask has been crafted for divers who want a wide front lens 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 UC-3125QB is a good match with our UF-21 fins.
