The SEAC Sonic Silicone swim goggle has an oversized and durable frame that reduces drag for competitive, fitness and recreational swimming. The comfortable leak-resistant hypoallergenic bio-silicone skirt and crystal clear wrap-around lens provides clear 180-degree visibility. The Pulsar buckle system allows for quick strap adjustment with just a touch, in or out of the water. Full 180-degree strap rotation makes the Sonic very comfortable to wear. Anti-fog and scratch resistant lenses provide 100% UV protection.
