Rainy days? Bring them on.<\/strong><\/h1>\n

Since launching in 2017, Grass & Air<\/a> 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 \u2014 and one of our most asked-about, too.<\/p>\n

So, how does the magic work?<\/p>\n

 <\/p>\n

What Is Water-Activated Colour Changing Technology?<\/h1>\n

In true Grass & Air style, it\u2019s where clever design meets everyday adventure.<\/p>\n

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 \u2014 changing from crisp white to vibrant, multi-coloured raindrops in seconds.<\/p>\n

And when everything dries? The design resets back to white, ready to do it all over again.<\/p>\n

Rain on. Dry off. Repeat.<\/p>\n

It\u2019s innovative kids\u2019 rainwear that doesn\u2019t just protect from the elements \u2014 it plays with them.<\/p>\n
