Mr Duyvken is selling these cycling jerseys through Velociti, his cycling blog. They're a little different from the other jerseys out there and are great for people who don't take themselves too seriously. The Republic of Anaerobia one is my favourite, I love the red blood cells and the cold war aesthetic.
If you're interesting in buying one and helping me get the huge box out of my bedroom email me or follow the links on the Velociti blog. They're only AU$85 each including postage which is a bargain for a quality cycling jersey.
