The Hyperlite Youth Indy HRM Neo Wake Vest is ergonomic and quick to drain. That means it brings maximum comfort to smaller riders out for a rip. More importantly, it's a fully US Coast Guard and Canada Transport Approved floatation device to keep your kid safer when they're out in the water. The Youth sizes are smaller than the Junior size, but larger than Child size, perfect for bigger kids between 50 - 90 pounds.
