One of our favorite masks for smaller narrower faces. The Single lense allows for a large field of view. The M-111 Kleio II mask is made from the same high quality materials as TUSA's standard size masks. The M-111 is perfect for smaller female and youth divers or snorkelers. This mask is defined by its low volume, snug-fitting design. Like all TUSA masks, it incorporates a wide range of features to enhance comfort, fit and provide clarity of vision.
