After an hour of painstakingly starching their shirt and polishing their leather Derby shoes, certain basic bros think it’s acceptable to throw on a very, very sad, several-year-old fleece for their commute, or team brashly branded chunky sports gloves with a tailored suit. The devil is in the detail, gentlemen, and one ugly technical piece can ruin the outfit you spent so much time laying out on the bed the night before.

“A simple thermal layer under your everyday wear is much better than functional clothing choices that lack flair or style,” says Street. Uniqlo’s HeatTech range is practical yet discreet and comprises fitted tees, vests and long johns (yes, you read that right – just like granddad wears) designed to be worn comfortably, and without destroying your silhouette.

As for outerwear that performs on both fashion and function counts, the classic down-filled gilet is a practical piece that’s stood the test of time, with this season’s advocates including contemporary labels such as Maison Kitsuné and A.P.C. through to outerwear specialists like Moncler and Canada Goose.

Not a fan of the body warmer? Thanks to the rise of trends such as sports luxe andathleisure, we’ve never been more spoiled for choice when it comes to performance jackets that look as good as they perform. Crafted using advanced space age materials and construction techniques, they’re not only lightweight and versatile, but designed to provide an impenetrable shield against the elements.

Leaders in the field include Stone Island, Arc’teryx, Stutterheim, Patagonia, Rains and Nanamica.
