The Tusa Kleio II mask is designed for smaller, more narrow faces and is made from the same high quality materials as Tusa's standard size masks. The Kleio II is perfect for smaller female and youth divers or snorkellers. 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. Panoramic View Panoramic View masks feature a variety of designs offering an incredibly wide field-of-view. Several designs incorporate minimum frame volumes, domed side-windows, reduced frame structures as well as three and four window styles for maximum vision. TUSA Round Edge Skirt Round Edge Skirt TUSA's Round Edge Skirt features a proprietary round edge cross-sectionally shaped skirt. This rounded edge results in a soft fit that suppresses pressure and reduces creasing left on the face. The "planar fit, instead of linear fit" silicone skirt maintains great fit and unprecedented comfort.
