Why Wear a Nose Clip?
Though most competitive swimmers don't make use of nose clips due to added drag, fitness and recreational swimmers often enjoy the benefit of sealed nostrils - no water entry whatsoever. Beyond that, any synchronized swimmer will tell you that a nose clip is essential for performing propulsive moves underwater.
Materials & Styles
Made from plastic, rubber, or silicone, each clip has its advantages. A clip with a metal structure is adjustable and can be bent to accommodate differently-shaped noses. A plastic clip is not adjustable but may be more durable over time. Clips with nose pads, like the Barracuda Nose Clip, are ideal for lasting comfort on long swims. Some clips come with a storage case or a built-in headband for security, though most come sans-strap.
