Father-and-son team Keith and Chris plan to make money from sweat. A few minutes under the scrutiny of the Dragons sees them shedding pounds.

An excited pair introduces their disposable vest that helps burn more calories when exercising. They claim interest in their product from top football and rugby clubs, athletes and celebrities.

Before Peter Jones can concentrate on the product, he wants to remark that Chris looks like Rugby Union star Jonny Wilkinson.

Peter asks how Chris came up with idea and brought his father in. Chris explains that the vest is worn once and thrown away. It is sold in packs of 10. At around £10 for a ten-pack, Peter thinks this is expensive.

Duncan Bannatyne asks how the vest helps lose weight. Chris explains the biology behind it. The body burns calories when sweating. Duncan has read that sweating just displaces water which is replaced by drinking, but Chris rebuts that idea.

Deborah Meaden asks about their financial details. They have made a loss so far. Keith says they will have cleared their debts and start to make profits this year.

James Caan wants to know when he'll make a return. Keith says in the second year he'll make that amount back. When James asks how that works, Keith's figures don't back up his claim and he vacillates.

Deborah is not impressed. She thinks it's nice to see a father and son in business together, but Keith's figures make her declare herself out.

Peter Jones says they're overvaluing their &quote;fashionable bin liner &quote; and is out. Theo Paphitis thinks Keith and Chris have nothing new here - anyone could have made the vest, and Theo declares himself out.

James isn't impressed either. The product, its market potential and especially Keith's waffle over the numbers ensure he will not invest.

Gym owner Duncan Bannatyne is the most likely Dragon to spot a sport-related opportunity, but there is no good news from him.

Duncan tells the story of research in the USA that found some people would use any excuse not to go to the gym. He says his training staff might use the vests but his customers wouldn't. He is out.

The deal done in the Den:

No investment
