SwimSchool's unisex Pink Mermaid Grow-With-Me Swim Trainer features a unique swim training system to grow with your child as they become more comfortable in the water. The swim vest provides supportive buoyancy and balanced flotation allowing kids to safely practice swimming and explore the water. Once your budding swimmer is ready, you’re able to zip off the arm floats from the trainer to help them easily and safely navigate the water as they become more familiar with swim practice. The 2-in-1 Tot Swimmer is recommended for children between the ages of 4 and 6 with a maximum weight of 50 lbs.
