The world's first 'self-cleaning' jumper has been unveiled - just in time for Christmas parties.
The high tech clothing rejects liquids and spills, and does not need to be washed for up to a month.
Liquid bounces off the surface of the clothing, made from polyester, without staining it.
Hopes are high it could be one of the most sustainable items of clothing ever invented.
Entrepreneur Varun Bhanot, 29, said: "We created a jumper and a hoodie range that repels liquids, dirts, sweats and odours, because you never really know what's going to happen on any given day.
"You could spill your coffee, spill some water, or maybe you're at a party and you might spill some wine down your jumper.
"You could wear it in the gym, or you could go out and about in it for more than a month and you probably wouldn't even need to wash it.
"After more than a year of experimentation, prototyping and fabric development we've created what we think could be the world's first set of self-cleaning clothing." He came up with the idea along with wife Anisha, 29, in a bid to help homeless people in Britain - but admitted that the jumper would be perfect for boozy Christmas parties if wine was spilled.
The couple, who live in Chigwell, East London, launched a charity together, Unhoused.org, to help rough sleepers.
Through the organisation, they are donating one hoodie to charity for every one sold.
Each jumper costs £69.99 and the couple believe it 'could be the most functional and sustainable hoodie ever made'.
Nanoscopic fibres repel liquid, similarly to a lotus leaf, and when washed the jumper dries 40 per cent faster than regular clothing.
Varun said: "It could be a game-changer for sustainable clothing all over the world, and an absolute life-saver for the UK's homeless and those sleeping rough, who may not have access to washing facilities and need to be kept warm and clean all year round.
"What is great is for every single one bought, one is donated to the UK's homeless.
"We partnered up with a few shelters here in East London and the response from them has been one of a huge amount of surprise.
"Most of the stuff they get in tends to be second hand donations.
"They could have something which could keep them perpetually very warm, very clean, and would reduce the need for them to be constantly washing things in washing facilities and of course the environmental benefits that come along with that, really took a lot of these shelters by surprise.
"Even though we only launched it around a month ago, people have been absolutely astounded by the effect it can produce and also the longevity of something like this."
