Description The Cressi Ikarus Orion combo mask has a silicone skirt for ensuring comfort and a perfect seal. Thanks to the adjustable buckles, it is possible to adjust the length of the silicone strap. The lenses are made of tempered glass. The snorkel features a special guard on the top that protects the tube from the water. The mouthpiece is made of soft silicone for avoiding jaw fatigue. At the bottom, a purge valve makes it easy to purge the water from the snorkel.
