This adult onesie is made of 95% cotton/5% spandex fabric that stretches both lengthwise and widthwise for the most comfort for even the most active of littles! Each onesie has four strong metal snaps for a secure fit.
If you measure at the top of a size, it's best to go up one size :)
Care: Hand wash or gentle cycle in cold water with mild detergent. No bleach. Air or tumble dry.
