The Bestway Swim Safe Step B children's float vest is specially designed for the little ones to learn the basics of swimming and safety in the pool, as part of the step-by-step learning range. The Swim Safe children's vest is to start progressing from step B, since they allow your little one to move their arms and start rowing with their hands until they reach step C. The knitted fabric on the outside is soft and comfortable, while the foam pads inside will keep them floating on the water. Not only have they been tested for buoyancy, they also feature Ultraviolet Protection Factor 50+ for added safety. The buckle and adjustable straps allow you to tighten or loosen to the perfect size. Also, there is a self-locking zipper with a flap to keep it secure. It is for children 1 to 3 years old, weighing 11 to 18 kg. * This product has ASSORTMENT designs so the specific model / color cannot be selected.
