Holt Evans and Radu Zarnescu at Harmattan Design teamed up to devise the accessory, which allows the belt to adjust by just 5mm at a time, promising the perfect fit.
They wrote on their Kickstarter page: "In 2016 we launched 'The Indestructible' Kevlar(r) & Leather Belt right here on Kickstarter and it was a major success with almost 2000 backers. Our signature invention is the addition of a Kevlar(r) Core to classic belt construction. This material is the strongest textile ever made, stronger than steel but flexible and light ...
"For 2017 we're back with much more. This time our belt is the best product possible from all angles. One major innovation is the Automatic Track System that eliminates the 5 hole system. A classic belt is not really adjustable because holes are 1" ( 2.5 cm ) apart. Say you had a hefty lunch or lost a bit of weight. Adjusting by one hole up or one hole down is a big leap and usually improper for small modifications in waist size.
"Our track system has 1/5" (5 mm) increments that are well suited for waist size modifications that occur naturally throughout the day so as to be adjusted for Perfect Comfort at any time, truly adjust. If you've never owned this type of belt before, the level of comfort will blow you away, it really changes the way you feel."
The team have also developed a strap attachment type buckle, which will do away with belt sizes.
They added: "Having sizes means you can get them wrong and makes it hard to order a belt for someone else. Sizes also mean that if you are exactly in between you will be wearing your classic belt at one end of the 5 holes or at the other, not really elegant.
"Because we are an on-line company we believe that our strap attachment type buckle is the best way to go in order to have very happy customers. It's also perfect for elegance. No more short or too long belt ends and no more wrong sizes. We have tested our belts over the last 6 months and these buckles are as dependable as they are beautiful."
