The new Sprint Short provides buoyancy for your hips and legs while swimming. A perfect training tool for triathlete's training in the pool and looking to simulate the lift of a wetsuit. These shorts are also a versatile alternative to a pull buoy for any swimmer. Crafted from buoyant Yamamoto smooth-skin neoprene down the front of the short and super stretch around the sides and back, for a mix of speed and flexibility. The updated sides and back of the shorts allow for more stretch, providing a better fit across a variety of body shapes and sizes.
