“It’s the field jacket’s versatility, and the way it marries form and military-inspired function, that’s fuelled its recent resurgence,” says Giles Farnham, Head of River Island’s complimentary personal styling service, Style Studio.

Here’s how it’s done:

Off-Duty

The field jacket – like most menswear pieces on leave from army ranks – skews more casual than smart. Which means it meshes best with the low-key elements of your wardrobe like tees, casual shirts, knits and jeans.

“The simplest and most relaxed way to wear the field jacket is with a classic crew neck T-shirt or polo shirt, jeans and a pair of crisp white sneakers,” says Farnham.

“Keep it simple,” says Pinto-Hervia. “Although the field jacket may be neutral, it is still a statement piece you don’t want to detract from. Classic suede Chelsea boots, blue jeans and a crisp Oxford shirt is the perfect way to wear this trend.”

Layer Up

Best suited to lightweight cotton styles, this way-to-wear allows you to double down on defence from out-of-season winds, and look like a total don while doing it.

It works best executed with an unstructured blazer (either buttoned or unbuttoned); simply layer your field jacket over your smart-casual ensemble and leave undone to reveal the nattier gear beneath. Consider it your new high-low summer go-to.

Suited And Booted

Teaming an olive drab cotton field jacket with a navy two-piece is hara-kiri. But that’s not to say field jackets with tailoring is entirely restricted territory.

“With the introduction of field jackets in luxurious fabrics like suede, you can now wear this utilitarian piece to more formal affairs by ditching the blazer and pairing your jacket with a white Oxford shirt and tailored trousers,” says Farnham.
