Parents, male and female.


Our popular winter Sleep Onesie for babies, toddlers and kids now comes in Adult sizes too! Designed for parents who are up all night with a restless babe (we see you), the Sleep Onesie is a sort of adult onesie pyjamas that will keep you warm during evening feeds, overnight settling, camping trips or Netflix binge sessions on the couch. This one-piece sleeper for adults is made from and filled with GOTS certified organic cotton that is non-toxic and gentle on skin. The 2.5 TOG rating will keep you warm during sleep in temperatures of 17-22°C / 63-73°F, without blankets, or wear under blankets in cooler temps. The zippers make for easy dressing and breastfeeding. Big pockets complete your sleep ensemble to stash the spare dummy, your phone, tissues, lip balm etc.

Made from our signature stretchy organic jersey cotton with a roomy fit, you can pop your sweats or PJ's underneath for additional warmth. Don't forget to get the matching Sleep Onesie in baby, toddler, preschooler or kid sizes for some matchy-matchy family fun.
