The Seal XP Dark is a hybrid goggle that combines the superior visibility and exceptional comfort of the Seal Mask with the low profile and hydrodynamics of the Kaiman Goggles. It has a flexible, one-piece frame and comfortable, watertight skirt that provides for hours of swimming and water sports enjoyment. The low profile, wrap-around design of the Seal XP creates less drag, has greater hydrodynamics and is ideal for fitness swimming or swim training. The unique Plexisol® lens provides 100% UV protection and is fog and scratch resistant. The innovative easy-adjust buckle system of the Seal XP also allows for quick and easy adjustments - even while wearing the mask. Great for indoor and outdoor swimming.
