The classic ZIPPYUP original zipped babygrow is made from 100% cotton, supersoft for your baby's skin. The zip is concealed so it does not come in contact with your baby's skin and the tab at the neck makes sure the zip puller doesn't catch any little chins. Zipper is 2 way to help you make nappy changes extra quick! This denim blue babygrow has turn back cuffs on the sleeves to allow hands to be enclosed to stop scratching so you don't need separate mittens and they are long enough for your baby to have lots of hand room. ALL SIZES have built in scratch mitts, newborn to 12-18M. Perfect for eczema sufferers or if your little one gets chickenpox to stop scratching.
