UPGRADED CLASSIC: WWII US NAVY N-1 DECK JACKET

The N1 Deck Jacket was created by the US Navy for aircraft carrier crews who needed to start warm and dry in appalling conditions, yet be able to move freely without snagging on equipment.

As with all standard issue military gear, corners were cut for mass production.

This is where we come in. We take classic men's jacket styles and upgrade them in any way we can.

In this case, to make a Deck Jacket that's quietly luxurious, yet tougher than before, with masses of pockets, in eleven sizes.

TOUGH, WARM FABRICS

British Millerain dry-waxed tough twill cotton has a wonderful texture and can be machine washed.

Primaloft proves insulation for chilly evenings, Spring & Autumn.

Brushed pure cotton flannel lining finishes the balance of comfort with subtle masculinity.

11 sizes, for all men

We tailor for men from 5'4" to 6'10" tall.

With chest sizes from 36" to 56".

That means eleven sizes & free sleeve alterations, unique in jacket brands.

Importantly, we take time to tailor exceptional fabrics that drape flatteringly, not suck around the bits you didn't want to accentuate.

We make you look manly, in a "I want to feel good, but not look like I'm trying too hard" way.

If you're not sure of your size, we can check your exact size easily. Everyone here has been helping men with sizing for years.

SERVICE BY FRAHM STAFF

No bots. No outsourcing. All of our beloved service staff have been with us for years, helping thousands of men.

CHANGE YOUR MIND?

No problem. No explanation needed. Pre-orders can be cancelled any time. You get 90 days once you've got your FRAHM.

WE DON'T STACK IT HIGH, OR SELL IT CHEAP

Nothing exceptional was ever easy.

Great jackets don't sit on dusty shelves with half price tickets on.

We choose to be slow & expensive, to carefully build an extraordinary reputation for doing what we promised we would.

Our singular concentration on long term reputation, not weekly sales targets, means you get a far better jacket.

WHY PRE-ORDER?

NO DISTRACTIONS

FRAHM is focussed on doing one thing really well - we upgrade classic men's jackets styles. That's it.

We make each design once a year. Each one is spread across the calendar. We're not distracted by the constant pressure to create new fashion ranges every six months.

After we've delivered that year's edition to our customers, we re-launch the next year's edition.

WHEN SHOULD I ORDER?

The short answer is always as soon as you can.

We're booking production space and getting fabric made twelve months before they've even been made.

Options gradually run out as we tick down from 12 months ahead to the arrival date.

If you see gaps in the options of colour/size, etc, that's an alarm bell.

WHY IS EVERYTHING 20% OFF?

That 20% discount doesn't mean we're in a Sale. We don't do them. We don't overbuy! That's your pre-order reward.

You help us, we help you. Fair.

If there's any stock left, or rare returns, they are at full price.

Another Belter

As a fully signed-up Frahm jacket junkie, this one is already one of my favourites - it’s so comfortable and I get jealous comments from my wife. It also feels like it will last forever which is the dichotomy for a junkie: I have 7 and now it’s becoming a little embarrassing

Usual impeccable standards

Been eyeing this jacket for quite some time and for some unknown reason, I bought it for my son. He absolutely loves it. Already his go to jacket and as we live up north , the sun has yet to make an appearance so it’s never off his back. This is my fifth purchase of a jacket and the quality / finish is second to none. They just ooze class. It won’t be my last , or his for that matter. Still need the Harrington….
