Back in the day - well, about 15 years ago - Global Hypercolour t-shirts were all the rage.
Well, it looks like Stone Island designers have been reliving their youth with this latest piece.
Previewed as part of the label's Autumn / Winter range, SI's latest ice jacket changes colour when you come in from the cold - as illustrated by the (albeit slightly wonky) ad video below.
As always with Stone Island, you can expect a high quality garment - and this new ice jacket will certainly turn heads.
And, if you don't like the colours, try the Liquid Reflective jacket in the same collection.
It might cost a little more than your old Global Hypercolour top mind.
