Start your underwater adventure with the TUSA Imprex Adults' 3-D Purge Mask and Dry Snorkel Combo. This combo includes a mask and snorkel constructed from pure silicone and polycarbonate material for durability, while the 2-window design with ClearVu tempered glass lenses provides a wide field of view for increased visibility. Hyperdry Elite Dry Top technology helps keep water out of the snorkel, and the high-flow purge valve and drain chamber allow for quick clearing.
