The Wahu Volleyball is the ultra, all-weather ball for play at the beach, pool, backyard, park or lake! Its neoprene skin is 100% waterproof, and it's soft on your arms to help reduce unwanted "sting." Contrasting colored and white panels allow you to see the "rotation" or "spin" on the ball in the air. This regulation size 5 Volleyball (8.3"/21.1cm diameter) is designed with a butyl air-filled bladder for high performance and hours of play! Includes 1 Wahu Volleyball. Recommended for ages 5 and up.
