Menswear is born from function. Unlike womenswear, whose only real concern is aesthetics, our enduring pieces have always done a job. And thanks be, too. Where the fairer sex are often left crippled by heels or shivering in slips, the male wardrobe boasts flight jackets originally crafted for frosty cockpits; trench coats as protective now as they were in WWI; and leather jackets that offer the edgiest way to deflect the weather.

But while Barbour’s motorcycle arm, Barbour International, is rightly famed for its iconic biker jackets, today the brand offers something for top to toe. The entire collection is crafted with the kind of care – and with the kind of fabrics – you’ll appreciate when you’re nudging the speed limit with nothing between you and the elements. But because it’s Barbour, it also looks just as good if you travel by Oyster card, rather than on the back of Triumph.

To celebrate the launch of the SS16 International collection, we’ve picked out the pieces worth investing in.

Original Wax Jacket

Barbour’s original biker jacket is as lustworthy now as it was on launch. If you’re actually astride your Triumph, then you’ll appreciate the belt and storm fastening, which ensure the wind stays where it’s meant to, even at high speed.

If you deploy your Oyster card more than your clutch, then say hello to your new three-season layering piece – it’s lightweight and waterproof, so perfect for slinging on over a tee when spring’s weather is hard to predict, but roomy enough to slot a pair of knits under when the frosts come back.

Available at Country Attire, priced £211.61.

1936 T-Shirt

This tee shines an appropriately revenant light on the year Barbour International sprung into being, with a subtle ’36’ emblazoned beneath the bike’s saddle.

It’s also cut from super-soft cotton, which makes it the perfect piece to layer beneath an open biker jacket. Well, if you’re going to show your allegiance to a biker brand, you may as well go the whole hog.
