The combo is the union of two high-quality products made from premium materials and featuring great design. The product is ideal for scuba diving, snorkeling, and freediving. The mask and snorkel are made of 100% high-quality silicone, a better and more durable material than PVC plastic. The snorkel has a float mechanism that closes immediately, preventing water from entering the snorkel, whether it has been submerged accidentally or intentionally. The snorkel features a highly flexible tube that reduces jaw fatigue and can be compactly folded for storage in a BC pocket or travel backpack. The wider elliptical opening of the snorkel increases airflow capacity for more comfortable breathing, and a purge valve allows for immediate clearing when needed. The mask is made from hypoallergenic silicone to ensure comfort and a perfect seal. It features angled and inverted tear glasses for better downward visibility, a patented design by Cressi. The lenses are made of tempered glass. The easy-to-use integrated buckles are built into the frame and have a rotating system for quick adjustment of the strap length. The combination comes with a practical bag for protecting and transporting the equipment. The Big Eyes Evolution+ Alpha Ultra Dry are developed and manufactured in Italy by Cressi, a brand that has been pioneering diving, snorkeling, and swimming gear since 1946. The product is covered by a 2-year warranty.
