the JAC

One of one  ·  Made to be seen

TheSports HybridJacket

Bespoke piece of wearable history. Each JAC is a unique jacket, made from your own blazer and a sports memory that matters to you.

02 - How it works

The JAC preserves a story
in a one‑of‑a‑kind piece.

Your existing jacket - beautifully customised by combining it with the sporting top you love, but never wear. Your story front and centre.

Your memory piece

The shirt you can't part with and never wear. A number, a crest, a race, a team.

Your JAC

Individually designed, cut and sewn into one jacket you'll wear on repeat.

An exceptionally striking jacket that gives two things you already own a whole new edge and dimension. This is much more than upcycling - this is precision, detailed, tailoring customisation.

03 - The origin story

Two wardrobes.
One jacket.

There were two versions of the same woman hanging in one wardrobe.

Kay in the number four shirt, lined up with the Guernsey touch rugby team in Paris, 2008

One was a black suit jacket. Sharp shoulders, clean lapel, cut for the boardroom, but over the years had simply become a little too ordinary. The other was a green number four touch rugby shirt: worn representing Guernsey at the Euros in Paris 2008. Memories made to last a lifetime, a shirt that represented more than an island team. A number that stopped meaning a position and started meaning an identity.

One was now overlooked. One was folded and never worn at all. Both were kept, for exactly the same reason; neither could be given away.

The JAC came out of refusing to choose. Not a patch, not a memento in a box, not a keepsake quilt. A jacket. Deconstructed and then recreated. Properly drafted, properly panelled, properly finished with the shirt's colour running through the style lines and the cuffs, the number carried on the back where it always was.

Minimal additions, minimal waste. And the result was the thing neither piece had been for years: worn, constantly, on purpose.

04 - JAC stories

Every JAC, and the
story it came from.

No two are alike, and none of them are meant to be. Each one starts in somebody's wardrobe and ends up somewhere they never expected to wear it.

05 - About - Kay Davidson

Why this,
and why me.

I've spent my career in fashion design and sustainability, drawing for brands, advising on supply chains, and talking, often quite loudly, about what the industry does and doesn't own up to. I can smell greenwashing a mile off.

The JAC is the least abstract answer I've found. It doesn't ask you to buy better. It asks you to look at two things you already have - one you seldom wear and one you can't let go of - and lets me turn them into a single piece with a whole new life ahead of it.

Using what already exists. Finding the best utilisation of your memory piece. I add the design and the tailoring, which I take extremely seriously, creating one-of-one by hand. Detail obsessed, finished to a standard beyond what the original jacket was made to.

It's sustainability you'd want to wear anyway. That's the whole point.

08 - FAQs

The five things
everybody asks.

What do I actually send you?

Two things: the jacket you would like customised, and the memory piece you can't part with. A blazer, a tailored jacket or a smart coat works best; the memory piece is usually a playing top, squad tee, race shirt e.g. marathon or cycling top but we can also work with any favourite clothing item.

We will send you pre-addressed, tracked packaging for you to pop your items into to ensure they arrive safely and promptly at the studio.

If your memory piece is too precious to be cut up - talk to us - we can arrange for a copy to be made.

What is actually involved to create each JAC?
  1. After we have received your pieces we will photograph them and create a digital design for you to approve, making the best use of your memory top and our creativity, adding taping and trims to complement and enhance. Nothing is cut until you have signed off the design.
  2. We then create individual pattern pieces to your blazer/jacket.
  3. The memory piece is cut to your specific pattern, and the pieces are then strengthened and taped as required. We don't add patches, we make sure your memory piece blends and flows exactly like your original jacket would.
  4. The lining is removed from your jacket, as all work is done from the inside to give an invisible and perfect finish to your JAC, and then the panels are attached.
  5. The sleeves are adjusted to accommodate the new sports stretch cuffs.
  6. The JAC original label is added to the lining and then it is reattached.
  7. Final press, wrapped and delivered back to you in our plastic free packaging.
What if my jacket doesn't fit me anymore?

Often fixable. But depends upon each individual jacket and person, plus there is an additional cost. Send your measurements with your enquiry and we'll tell you honestly what's possible before you commit.

How long does it take?

Each JAC is individually designed and made by hand, and there's already a wait list of orders to be made. Expect it to take from 4 to 6 weeks after we receive your items. You'll be given a more accurate date at the point of receipt and you'll also need to approve your design before any cutting can start.

The JACs will be made in either London or Guernsey and we work internationally so shipping times are in addition to the time required in the studio and workrooms.

What does it cost?

Pricing will be confirmed at launch and will depend on your particular JAC pieces and the work involved. A simple panel-and-number is not the same job as a full conversion. As a guide: prices will range from £175 to £300. We are working on a detailed price list and will publish when available.

Those who sign up with us pre launch will receive a discount on their first JAC purchase of 20%.
