A deep navy keeps the Girls Navy Blue Shark Onesie looking clean after tea

Navy sits between the bright blue children ask for and the grey parents prefer, which is why this navy blue shark onesie for kids works so well in a house with several opinions. The body is a deep sea navy with a white belly panel, and the hood carries a round eye, white teeth and a red mouth behind them.

The pile is deeper than a standard flannel, so the warmth arrives immediately in a cold bedroom. The cut stays loose at the knees and elbows, the cuffs hold the sleeves in place at the table, and the whole piece goes back into the machine whenever the day has been messy.

Boys Navy Blue Shark Onesie for playtime that runs into bedtime

These kids navy blue shark pyjamas are built for the hours where playing and sleeping blur together, which is exactly what a children’s shark onesie has to survive. The hood stays up while your child runs from room to room and the fabric never itches.

It also travels well, since it doubles as pyjamas and as fancy dress for whatever the weekend turns into. Order it for a birthday, a winter holiday or a cousin who already has every blue onesie on the shelf.

Navy for the whole family

The baby navy blue shark onesie carries the same navy down to the youngest. For the brightest version instead, the kids blue shark onesie keeps the classic ocean blue. Line them up in the shark onesies collection.

Frequently Asked Questions

They’re made to keep you warm on the sofa through autumn and winter, so yes, they’re cosy. The relaxed fit lets air move around, though, so you won’t get that stuffy feeling you get from tight pyjamas.
Machine wash at 30°C on a gentle cycle. Turn them inside out and pop them in a mesh laundry bag to protect the hood. Skip the tumble dryer and the iron. They air-dry quickly and fluff right back up on their own.
Yes, every onesie we sell is unisex. The roomy cut works for men and women alike, our kids’ styles fit girls and boys just the same, and our baby sizes are cut the same way for everyone. Just check the size chart to find your fit.
