Since launching in 2017, Grass & Air have been on a mission to turn grey skies into colourful adventures. Their signature water-activated colour changing technology has become one of their most-loved innovations — and one of our most asked-about, too.
So, how does the magic work?
In true Grass & Air style, it’s where clever design meets everyday adventure.
Their water-activated colour changing technology reacts when it gets wet. As raindrops hit the print, hidden colours burst into life. Patterns transform before your eyes — changing from crisp white to vibrant, multi-coloured raindrops in seconds.
And when everything dries? The design resets back to white, ready to do it all over again.
Rain on. Dry off. Repeat.
It’s innovative kids’ rainwear that doesn’t just protect from the elements — it plays with them.
From concept to creation, the Grass & Air product development team designs everything in-house, exploring new ways to reimagine waterproof outerwear for kids.
They believe rainy days are full of possibility. That’s why their colour changing prints are created with two goals in mind:
Whether they’re splashing through puddles, racing down park paths, or heading off on woodland wanders, their colour changing designs make every drizzle feel like a discovery.
Because let’s be honest — if the rain’s coming anyway, it might as well put on a show.
There’s nothing quite like seeing it for the first time. One moment it’s white. The next? A kaleidoscope of colour appearing as if by magic.
Grass & Air’s colour changing wellies, children’s umbrellas and raincoats are designed to transform with every splash and shower — turning everyday rainy day activities for kids into something unforgettable.
Looking to brighten up your little explorer’s wardrobe?
Each piece is crafted for comfort, durability and plenty of puddle-jumping potential.
So next time the forecast says rain? Pull on the wellies. Pop up the umbrella. Step outside.
