Comfortable and offering plenty of freedom of movement for the arms, this vest is the ideal swimming aid for children. The adjustable leg strap allows it to be secured to the body, preventing it from slipping. It features a zipper (vest) and a quick-release buckle (leg strap) for easy putting on. Variable buoyancy elements ensure optimal, flexibly adjustable buoyancy. Please note that the guaranteed buoyancy is only achieved when all buoyancy elements are used.
