With temperatures continuing to drop across the Northern hemisphere, unfortunately it’s time to put away the light autumn jackets, and bring out the winter thermals.

If you suffer in the cold, Columbia Sportswear’s new jacket could be just the thing.

The high-tech jacket features ‘Omni-Heat Black Dot technology’ that promises to keep you warm, even on the coldest days.

As the name suggests, Omni-Heat Black Dot technology is a textile covered in multilayered black dots that capture solar heat and keep you warm.

Dr Haskell Beckham, Columbia’s Senior Director for Apparel Innovation, said: “To maximise a shell fabric’s heat retention, we looked closely at low-emissivity windows that rely on a thin layer of metal on the glass.

“We’d never seen insulation placed on the outer layer of a jacket before, and we’ve been extremely impressed with the heat absorption and retention performance throughout our testing in the laboratory and in frigid climates around the world.”

Each dot is made of aluminium and covered with a black coating to enhance heat absorption for scattered or direct sunlight.

This allows the jacket to heat up quickly and retain heat, keeping you nice and toasty.

The Omni-Heat Black Dot technology isn’t the only feature to help keep you warm though – the jacket also has a reflective aluminium lining covered in fuzzy fibers.

The lining bounces back the body’s own heat, while the fuzzy fibres help to retain this heat.

Unsurprisingly, the jacket isn’t exactly cheap.

It comes in two styles – a quilted version called Three Forks Black Dot Jacket (£270), and a longer version called Dawn Watch Black Dot Jacket (£315).

Mirror Online tests the Omni-Heat Black Dot Jacket

Mirror Online's Shivali Best tested Columbia's new jacket this week, and it was a resounding success.

Despite featuring heavy insulation, the jacket is surprisingly light, and could easily be bundled into a bag if the sun makes an appearance.

While I was initially skeptical of the shiny outer material, it was actually quite fashionable and would easily match most outfits.

In terms of warmth, the jacket is pretty incredible.

The combined forces of outer and inner insulation result in a gloriously toasty experience, while the detachable hood offers even more protection against the British weather.

London is currently only 10°C so the heavy insulation was perhaps unnecessary, but with temperatures dropping by the day, this jacket could be the perfect thing over winter.

With a price tag of £315, the jacket definitely isn't cheap, but could be a great option for people who really feel the cold, or for those who live in an area that is cold year-round.
