Did the West bought for our very active little (1 3/4 years) and safety even for the Great (6 years) and both have carried them in our sea vacation often. Are obviously very comfortable, dry quickly and the snap lock under the Zipp can even be locked. By the belt between the legs, the vest can not slip over the head. Thus on the Pool Terrace Breakfast was possible without bulky swim rings were a hindrance when playing. Great!
