The Zoot Ultra Buoyancy short promotes optimal body position to take your swim training to the next level. By naturally elevating your body/legs and lifting your hips up, the shorts place you in the fastest position possible. Promoting this optimal body position in training creates muscle memory that allows for a more efficient stroke on race day. Designed with the same high-end Yamamoto materials as all of Zoot Wetsuits, the Buoyancy Short is durable and will hold up to hours of pool and open-water use.
