Designed for use with car seats, this One Piece Baby Snowsuit Sky Blue features a crotch opening that allows the belt harness to be routed through the snowsuit and buckle the belt directly on the baby's body. This also allows you to leave the front panel open so that baby does not get too hot in the car. Oh-so-cute in a cozy one-piece silhouette, this insulated snowsuit is designed to keep little ones warm in temperatures as low as -30° C (or -22° F). Our snowsuit features an attached hood and a soft velvet lining. It's detailed with an adjustable waist, overlap mitts, attached ankle booties, and a coordinating sherpa neckwarmer.
