Alrighty I've just about seen all the Pump collabs I want, about 15 no doubt, so far.
Here are my favourites:
24 Kilates : The Spaniards capture the simplicity of the original cw, while highlighting the celebratory fact of the matter, The Pump technology, using translucent black paneling to reveal the inner workings of what Pumps up, and air's out.
HUF : Solid, Simple, Seductive. I expect nothing less from one of the classics of my wardrobe.
