A swimming device designed to more easily facilitate the ingestion of air during the act of swimming is disclosed. The device permits the user to expend less effort breathing and focus more attention to the motor activity. The device improves the existing art of recreational snorkeling devices since its design is less cumbersome, more hydrodynamically streamlined, and causes less fatigue to the mouth and jaw muscles. The device of the invention consists of two flexible breathing tubes which encircle the user's head from the mouth, pass below the ears, join and pass through an adjustable slip piece, and then project upward and forward above the rear portion of the user's head to permit air induction free of water. At the interface of the mouth of the user, the breathing tubes are joined by a mouthpiece which has a small ribbed tube for the user to hold the device with his teeth. The device when properly tensioned with the adjustable slip piece provides a snug and self holding fit which requires no clenching of teeth or lips to maintain the position of the device. When the device is loosened by moving the slip piece along the tubes away from the mouthpiece, it easily stores around the user's neck and is independent of swim goggles or a snorkeling mask.
