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

The Grey Hare design
Hares are born with fur and open eyes, ready to run within hours, unlike rabbits. A fast, long-eared design for the tortoise-and-hare play and spring parties.

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.

The hare in the big race
Class play of the tortoise and the hare, and she was the hare. She lost the race on stage as scripted and took it very seriously.

Born ready to run
Told him hares can run within hours of being born. He has not stopped sprinting since he put it on.

Those long ears
The long hare ears are what sold it. She checks them in every shop window.

Hare, not rabbit, thank you
My son corrects anyone who calls him a bunny. He is a hare, and the grey suits that perfectly.

Muted grey I liked
Nice to find an animal onesie that is not bright pink or blue. The grey is soft and easy on the eye.

Six washes in, cold and inside out, and it is still lovely and soft.

Sixth birthday hare
He wanted something different from all the bunnies at nursery. The grey hare was his birthday pick.

Frosty bus stop
Wore it under his coat at the bus stop on a frosty morning. Toasty.

Not for bedtime
He asks to sleep in it every night. It is loungewear, so it goes on the chair until morning.

Her brother has the white bunny and she has the grey hare. They argue about who is faster.

Animal costume day and she went as the hare. The teacher used her to explain the difference between hares and rabbits.

Going up a size means the sleeves are long for now. Rolled cuffs until she grows.

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.
How long does delivery take?
