Made from silky smooth bamboo rayon, our innovative, new version of the traditional gown keeps baby's feet tucked in, limiting the chances of a rogue foot slipping out and catching a chill. With a single snap, release the bundle and flip it back for easy diaper changing. The stretchy material gives you the option to have a snug or looser fit while still staying comfortable and cozy.
