Life saver, literally
We love these! This is our second purchase because they lasted for 3 summers prior. My kids are comfortable in them, they swim super easily and continue to wear them out of the water

Price checked 2026-10-05; our partner store sets the final price and it can change.
Seafoam Blue is the calmest color in our vest lineup, and this Medium/Large size carries it up to 50 pounds. It is the same Flex-Form trainer families know, cut for a bigger, more ambitious swimmer.
- Medium/Large size fits growing swimmers up to a 50-pound maximum.
- Covered heavy-duty zipper and padded shoulders make it easy to wear.
- Padded safety strap adjusts to keep the vest securely in place.
- Built-in foam pads are balanced to hold a prone, ready-to-swim position.
- Sun-protective UPF 50 fabric in a soft Seafoam Blue shade.
In the water with it
This Medium/Large vest suits children who have passed the 33-pound mark, with a maximum of 50 pounds. As a Level 2 trainer it supports your child in feeling comfortable in the water. The shoulders are padded, the heavy-duty zipper is covered, and the adjustable safety strap is padded too, so the fit is secure but never scratchy.
In the pool, the Flex-Form foam pads balance flotation and settle your child into a prone swim position. The soft, form-fit fabric is designed to propel them forward, which promotes using arms and legs the way swimmers do. Its UPF 50 rating protects the upper body from the sun while you coach from close alongside.
LEVEL2
Build Swim Skills
Level 2 starts with a sweater-fit tot trainer that goes on like a favorite top, then moves on to a swim trainer vest with Flex-Form foam and an adjustable safety strap. With that support around the chest, play turns into paddling without anyone calling it a lesson.
