The Ondina is the smaller version of the popular Onda mask, suitable for young people and women with narrow faces. This mask has a single lens, and is designed for snorkeling, swimming and scuba diving. The visibility provided by the single lens and the unusual shape of the frame extends in all directions. Thanks to the mono-lens the field of view is wide. The skirt is made from soft hypoallergenic transparent silicone. The silicone is the best material because it is softer, compared to the standard PVC, and ensures a perfect seal on the face. Mask has an easy-to-reach one-hand nose pocket for ear equalization. The buckles system allows to easily adjust the length of the mask strap.
