Our kids need to wear a lifejacket when we're in or just around water, aboard a vessel, or in a waterpark. Even if they know how to swim, it's better to be cautious in all situations. This beautifully designed blue Yon Sub Kids lifejacket is made for ages more than 3 years old and made durable for your kids' security. This lifejacket is made of Neoprene SBR +EPE diving materials, which made this an even more wearable, easy to clean, lightweight, and comfortable protection gear. This is also helpful for your kids who are learning to swim.
