JEANS. We all own them, and for most of us they're our go-to item of clothing when we can't be bothered thinking up anything else to wear.

But for Matthew Scott, his love affair with denim goes a little bit further. 300 days further, in fact.

To raise money for Jeans for Genes day, an Australian charity which supports children's medical research, Scott decided he'd do something a little bit different.

"Well, I work as a Denim Manager for Glue Store so I'm all about jeans, and we've been involved with Jeans for Genes for a few years now," the 27-year-old told news.com.au.

"Last year I thought, what can I do to help the charity that's a little bit more than just collecting funds? And I came up with this idea," he said.

So, Scott donned a pair of Denham 14 ounce Japanese denim jeans and kept them on right up until August 2, wearing them rain, hail or shine - literally.

"Summer was definitely the hardest. I've worn them to the beach, out at night, through that 46 degree day which was hottest day on record - I tried rolling them up as far as they could go, anything to cope with the heat! I was the only person not wearing shorts at a festival during the summer as well, and I definitely got some weird looks.

"I've been pretty good about not spilling stuff on myself so there haven't been many disasters there. But I went on holiday with my friends to a really small country town in North West NSW and I thought it'd be a good idea to scout the surroundings by climbing a tree. Anyway, it was no surprise that I tore them on my way up and I spent a couple of weeks with a blown out crotch until I could get it mended.

"Hopefully I don't smell, I haven't washed them but I have used Mr Blacks, a Melbourne product that kills all the germs on denim, and that seems to have worked so I haven't lost any friends" he said.

But seeing as Jeans for Genes day is today, will removing his denim be bittersweet?

"Not really," says Scott, "though I have enjoyed it. My first motivation was to raise money, but it's been exciting getting that true raw denim experience. Denim is all about creating a story on a canvas, the rips and the tears fabric gets. It's all about character. Because of that I was tempted to keep running through until 365 days, but I think it's time to shut it down!"

In Australia, 1 in 20 kids are born with a genetic disease or birth defect. If you'd like to contribute to the Jeans for Genes day cause, you can donate to Scott specifically here, or donate to the organisation here.
