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.

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 DO I KEEP SEEING 20% OFF?

That 20% discount doesn't mean we're in a Sale. We don't do them. We don't overbuy.

That's the pre-order reward on FRAHM Jackets (but not on collaborations).

You help us, we help you. Fair.

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

My best Frahm jacket yet

Everything about this jacket is spot on. The fabric, the fit, the comfort, the details. I have a couple of other Frahm jackets so I knew to expect something good but this one really is just so right in every way. Love it.

Deck Jacket

It fits well, is warm and comfortable besides being well priced.
What is not to like?

Impromptu Archive Sale Purchase

Yes, I fell or it! Persuasive bunch, or just great marketing? Another great jacket. It has some weight to it, so will great for those cooler days. Moving to Emden on the north German coast, so it will be perfect. AND, after some painful German import tax bills to pay on my first two Frahm jackets brought earlier this year, it arrived tax-free!

More of the same

Might seem an odd title but it really is. Another beautifully made and designed jacket although a little stiff to start with it’s loosened up with use to become a go to for all occasions.

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
