"They said 'he loves your design aesthetic, and the lines on your garments, and would love to have one of your products on the catwalk for his fashion show in New York.
"We had ten days to design it, get it manufactured in Asia, and then shipped to New York."
The team designed more than West had asked for, just to make sure there was something included that he liked.
It was all worth it when the team saw their work sent down the runway, with logos intact.
"Most of the time, this kind of thing, they want to take your logos away or cover them up," Hunt said.

With the tight deadline, Hunt hadn't had time to realise how big the exposure would be for his company.
But his family soon set him straight.
"Honestly, I'm a 44-year-old father of three daughters, so I know who he is but I didn't realise how big it actually was.
"When it came out I was having dinner with my daughters, and the first things they posted on Facebook was 'Dad we're so proud of you'.
"After all the things I've done in my life, they're finally proud of me because of this one thing."
2XU is now moving its head office to Los Angeles, in order to create more opportunities for collaboration.

Until the contracts are signed, he can't reveal who it is.
But he's hoping to make the sportswear collaboration public around April.
