The ISC Reef Mask Snorkel Fins set is a high quality snorkel set. The mask allows for increased visibility and stays dry. The fins use technology introduced in 2016 to maximize thrust while minimizing effort and leg fatigue. Furthermore, the adjustable straps are engineered for comfort and help to prevent chafing. The snorkel features a soft silicone mouthpiece that is easy to use while a semi dry top helps to prevent water from entering the top. Conveniently packaged in a mesh bag.
