Deep navy flannel wraps the Newborn Navy Blue Shark Onesie

This navy blue shark onesie for babies takes the darkest shade of the range and makes it gentle. The navy pile is deep and soft, the white belly panel brightens the front, and the hood carries a small row of teeth above the face with a fin standing on top.

Everything is sized down rather than simply shrunk, so the fin stays soft enough to lie on and the teeth are stitched flat. The hood sits loosely around the head, which means it can be pushed back indoors without any fuss.

Infant Navy Blue Shark Onesie for pushchair walks and quiet naps

What makes these baby navy blue shark pyjamas practical is the zip that runs the whole length of the front, turning a change into a matter of seconds. An infant shark onesie has to survive the washing machine as often as baby life requires, and this one does.

Navy is also the shade grandparents tend to choose, and the one that hides the small marks of a day out. Keep it for a winter outing, a first fancy dress or the photo the whole family will ask for.

Navy from the smallest up

A parent can match in the adult navy blue shark onesie, cut in the same deep navy. For something brighter on a sibling, the baby bright blue shark onesie lifts the colour. The whole family line up is 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.
