TOG Guide
What is a TOG?
TOG stands for Thermal Overall Grade and is a unit of measurement for insulation and warmth of sleepwear and bedding. The lower the TOG rating, the lighter the fabric; the higher the rating, the more padded and insulated it is.
Size Guide
Sleep Onesie
Please use your child's height to find the most appropriate and safe size for them. The Sleep Onesie should be fitted around the neck to avoid your child slipping through. 2.5 TOG and 3.5 TOG Sleep Onesies should not be used in a 5-point harness or car seat for safety reasons.

Description
You asked, we delivered. Our popular winter Sleep Onesie is now available in kid sizes up to 12 years (and adult sizes too!). This TOG-rated onesie can now be worn by the whole family for sleep, movie night, camping, sleepovers, walking the dog - whatever takes your fancy we're here for it all. The new larger sizes are helpful for a preschooler who loves their pouch for sleep and doesn't want to give it up. They can now transition into the kid size sleep onesies with minimal disruptions to their sleep routine. Our kid-size Sleep Onesies have a front zip that ends at the crotch for easing dressing, and pockets for pockets sake (who doesn't like pockets). The Sleep Onesie is made from and filled with GOTS certified organic cotton that is non-toxic and gentle on irritable skin. The breathable, stretchy material allows you to move freely and stay comfortable.
The 2.5 TOG Sleep Onesie will keep your big mini warm in temperatures of 17-22°C / 63-73°F. The TOG rating means you can wear the onesie for Sleep without blankets. If using for camping, it's a great option for your big kid to wear in their sleeping bag as an extra thick pyjama. You can also wear a pair of socks for extra foot warmth on chilly nights.
The Sleep Onesie meets all safety standards in Australia and New Zealand, is approved by the International Hip Dysplasia Institute as hip-friendly for growing hip joints, and reviewed by the Eczema Association of Australasia as a skin-friendly product. All ergoPouch fabrics are dyed with non-toxic water based dyes, and come in trend-driven prints and colours. All our prints are designed in-house.
