FRAHM Deck Jacket in Black.

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.

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.

Heavy twill jacket

Great quality as normal, looks great. Comfortable. For me the only gripe would be the length. I’m 6f 3 and I find this jacket also the racer jacket just a bit short. Anyone over 6f 5 it would be to short. Apart from that a great jacket built to last many many years.

Feeling good

Super pleased with my jacket.🧥 Hard to explain it’s quite a sensory experience, feel, fit and looks you just want to put it on. 2nd jacket ordered. Thank you 🙂.

Heavy Twill

Can’t wait for the Spring to set in to put the Ventile Thermal and Ripstop Puffer away and put on the Heavy Twill. Fits perfectly and feels great on. Quality

Just feels great, cosy and comfy on my walk along the beach then up to the bookshop, in the 8 degrees feels like 4 degrees weather at the end of March. It’s not sweaty (like puffer jackets) and feels like I’m wearing smart menswear (dark blue version) not sportswear, or hill walking gear. The inner zip pocket is great for securing cards and the lower inner pocket is a good phone pocket; leaving the hand pockets free for my hands. Love the corduroy collar, especially when turned up against the wind.

Versatile - but I bought in Green!

I imagined this would be quite a short jacket, in fact it is about as long as the Original Utility Field Jacket. The fit is on the larger side compared to usual Frahm sizing and fits me well, especially across the shoulders. It has a superbly solid feel to it, and extremely useful, large pockets - the inner one holds my iPad mini with ease and now I rarely need to take a ‘man-bag’ with me. It has just the right amount of heft for a three-season jacket, and with a proper jumper underneath I sense it will do winter too. My new ‘go to’.

Exceeded expectations

Very pleased. The eternal dilemma of having to opt for comfort or style is emphatically resolved as this is both comfortable and stylish. Lovely and warm it exudes good taste. The pockets are very useful. What more can a man want? I immediately ordered another Frahm jacket. Roll on April 2026!
