River side parks are full of new friends, among them: brown trout, starlings and crickets. Extend nature's playdate with our Baby Lightweight Synchilla Snap-T Pullover, a lightweight, double-faced, recycled polyester fleece jacket (solids are bluesign approved) with the same durability and warmth as our adult version. The pullover has a 4-snap nylon placket, stand-up collar and Y-Joint sleeves for exceptional mobility. Left-chest snap pocket with nylon flap holds rocks. Spandex trim on cuffs and hem helps retain warmth. Hip length.
