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.

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 Deck Jacket - Another Classic from Frahm!

It’s made from top quality material, thick yet supple with a very nice grey dog tooth lining. The cut is sharp and stylish with the regular “handy” pockets for hands but this time line with corduroy just like the collar which makes it super soft and tactile. Perfect for chilly but dry spring and autumn days.

It’s a Religion!

Needed a jacket for the build up to the UK summer, received jacket two weeks ago and has become my go to, for when I’m walking the dog or going out to my local micro bars…this my 5th jacket from FRAHM, and attention to detail and the seasonal application and situational design is impeccable..

Best fitting jacket I’ve ever owned

This is the best fitting jacket I’ve ever owned. I think it’s the fit around the shoulders and under arm that I noticed most when commuting on London Underground - holding the bar above one’s head, the jacket keeps it shape. With other jackets and coats, that posture pulls up the whole garment. I like the fit around the torso as well, it’s a comfortable fit without being baggy. The material is clearly hard wearing and is going to last and last. The front pocket below the lapel is perfect size for my iPhone and a like the pen holder too which also doubles as a sun glasses holder. If I could, I’d make the inner breast pocket slightly wider to accommodate a leather wallet. Overall this is the perfect spring/autumn jacket for me - I went for black as it’s easy to match with a smart casual look for either the office commute or about the town of a weekend. Thanks to my brother for introducing me to the FRAHM brand.

Two jackets to rule them all

When I reviewed my black Deck jacket I said it had become my go to jacket. Well now I have two and other than choice of colour - black/olive green??? - it’s still the jacket I reach for when leaving the house. They’re both really great colours so it’s a very indulgent choice to have. The only thing I would change if I was selling and not buying the jacket is the name. Deck jacket with its connotations of naval activity just doesn’t do it justice. It’s for street, public space, public transportation, pub, any location or activity you can think of where you might need a jacket. It’s even showerproof. A truly great jacket.

Another Standout Jacket from Frahm

I've been pining for the arrival of this jacket for a good long time and I'm not disappointed now that I'm wearing it. This one is a bit different from much of the range in that the twill, corduroy and rivet buttons set it apart, as well as the styling.
No doubting the water resistance and that it seems both light in weight and warm at the same time - no doubt a testament to design and material choices.
Great jacket, once again
