The new Cressi Piuma Mask uses patented Cressi performance and design features such as an angled lens and inverted drop lens shape, but is used in a signle-lens mask design. Continuing in the rich tradition of Cressi masks, the Piuma uses proven technology and craftsmanship and updates it with new features and benefits. This is the newest mask in Cressi's line which features our patented 30% angled lenses for superior downward visibility. The inverted-drop shape of the lens is seen in a single-lens design on this mask, making the range of visibility even wider. This mask uses our newest buckle technology, which has previously been used on Occhio Plus and Ocean Eyes models. The buckles are integrated into the frame of the mask and use an extremely durable material which make them very flexible and virtually indestructable.
