Product description
The Koala Critter Onesie in big-kid sizes: a thick flannel jumpsuit with the full animal hood, for children 100 to 140 cm tall.

The Koala design
Koalas sleep up to 20 hours a day and get almost all their water from eucalyptus leaves. A sleepy Australian favourite for zoo trips and slow weekends.

Dress-up that gets worn again
A costume that is also comfortable is the one that comes out of the drawer after the party. Thick flannel and a roomy cut make this one a weekend-morning favourite as much as a costume.

Sized by height
Pick the size that matches your child's height: 100 cm through 140 cm. If they are between two, go up — it is a loose, relaxed fit by design.

Frequently asked questions
Which size should I order?
Match the size to your child's height in centimetres — a 115 cm child takes the 120. Between sizes, go up.
How do I wash it?
Machine wash cold, inside out, and let it dry flat or tumble on low.
Can my child sleep in it?
No. It is a costume and loungewear, not sleepwear. It is a loose, hooded plush garment; children should sleep in close-fitting sleepwear with nothing near the face. Take it off before naps and bedtime, and keep an eye on a baby in it so they do not overheat.
