Kids can build water confidence in this unisex Deluxe Pink Mermaid Swim Trainer Vest with Adjustable Safety Strap. Featuring Flex-Form™ Foam Technology which allows for movement with comfort, this playfully designed vest boasts supportive buoyancy and superior fit. The sturdy chin-up collar keeps little one’s head above water while they build familiarity with floating and swim practice. Once your child feels comfortable keeping their head above water, the removable collar can be used as a swim-chase toy. An adjustable safety strap keeps vest securely in place and a heavy-duty center zipper provides added security. The center zipper also ensures that the vest is put on and taken off with ease.
