Abstract: A swimming aid being configured to increase a user's buoyancy in the water. The swimming aid has a supporting structure with a back float. The supporting structure is designed to secure the swimming aid to a user's upper body. The back float is tiltable—seen in use—about a transverse axis connected to the supporting structure. The tilting movement of the back float to the supporting structure enables the user to obtain an inclined, more vertical posture in the water, which will improve the user's ability to keep their head above the surface of the water and also intuitively encourages the user to stretch out their hands to make a supportive movement with the hands in the water. Thus, the swimming aid increases water safety and at the same time promotes swimming skills.
