This front-entry child PFD is designed without in-water head support for older children who no longer need it or those who stubbornly refuse it. The ultra-soft, stain-resistant outer fabric is durable, while the ventilated mesh back and moisture-wicking liner are breathable and quick-drying. Segmented foam moves with your active child. The zipper and buckle closure with the leg strap creates an adjustable and secure fit, and a grab loop on the back allows you to quickly snatch them from the water in an emergency. The Child Rev Foam Vest is for users weighing 33-55 lbs (15-25 kg.)
