The Cressi Glide Swim Buoy is an essential part of the open water swim kit. Made of durable orange material, it's highly visible in the water, keeping you visible and safe. The Glide also functions as a floating dry bag. The roll-up top and clip closure form a tight seam, which means you can safely carry small personal items such as spare glasses, car keys or a GPS tracker while swimming. In low light, you can slip a flashlight inside to further increase your visibility. The buoy is inflated using an external valve. An adjustable hip strap and lanyard help hold and secure the buoy. For added peace of mind, the top buckle is equipped with a built-in emergency whistle. The Cressi Glide is ideal for open water swimmers who want a swim buoy to store items while swimming.
