Fyn Sleek Full PU
Fyn Sleek – The Compact Flap-Top Backpack for the 7:42 Morning
It's 7:42. Train at 8:04. The last thing you want is a backpack that needs convincing — wrestling a zip pull, fishing for the strap behind a coat, blotting last night's drizzle off canvas.
The Fyn Sleek by Kapten & Son is built for that exact morning. A magnetic flap that closes itself in half a second. A full PU coated shell that wipes clean with one swipe. Thirteen litres of flat Scandinavian minimalism, designed to disappear under a coat and reappear when you need a 16" MacBook out fast.
Who actually grabs it
The hybrid worker between an office day and a remote afternoon. The architecture student between studio reviews. The new parent who needs one hand free for a stroller and one bag that keeps quiet. Already a fan of the textile Fyn Backpack? The Fyn Sleek waterproof commuter backpack is the same silhouette in rain-ready PU.
Need more volume for laptop days? Step up to the Bergen Pro Sleek. Weekend escapes? See the Lund Sleek rolltop.
What actually matters
- A magnetic flap that closes itself — half a second, no zip drama, no Velcro tearing in a quiet train carriage.
- Soft-touch matte PU, fingerprint-proof — wipes clean with one swipe, the flap stays gallery-clean even after a rainy commute.
- Compact 13 L, fits a 16" MacBook and your day — 36 × 28 × 3 cm padded sleeve, plus an external slip slot for a tablet, plus 5 internal pockets for the rest.
- 800 g empty, hidden anti-theft pocket on the back — light enough to forget on your shoulder, secure enough to trust on a packed metro.
- Designed in Berlin, refined for the 7:42 morning — the silhouette Kapten & Son built around the minimalist commute, now in a rain-ready Sleek finish.
Quiet on the metro, ready at the airport
Goes from morning meeting to evening pottery class without re-organizing. Goes through airport security without getting flagged for a tangled mess. Goes under your trench in November and out clean in April.
Not the bag for a gym session, not the bag for a 70 L trek. The bag for the rest of the days — the 200+ days a year you carry a laptop, a charger, lunch and a book between three places.
Designed in Berlin by Kapten & Son. Limited release in All Black and Muted Rose only. Two colorways, while stocks last.

FAQ – Fyn Sleek
How is the Sleek finish different from the textile Fyn?
Same flap-top architecture, same 13 L volume, same back-panel laptop sleeve as the original Fyn — the Sleek edition swaps the woven shell for a full PU coating. Soft-touch matte feel, real water repellency, no woven pattern. Identical fit on the back.
Is the magnetic flap secure enough on a packed train?
Yes. The magnet pulls hard enough that the flap doesn't pop open under pressure or quick movement, and the Velcro under the flap acts as a secondary seal. The hidden anti-theft pocket on the back panel handles the wallet/keys layer.
Will a 16" MacBook actually fit?
Yes — the padded sleeve measures 36 × 28 × 3 cm, designed around the latest 16" MacBook Pro. A charger, a slim notebook, AirPods, and a slim water bottle still fit in the main compartment alongside it.
Personal item on a budget airline?
Yes — at 39.5 × 28.5 × 12.5 cm it fits the personal-item allowance on Ryanair small bag, easyJet small cabin bag, and most other European low-cost carriers. The trolley pass-through means it rides on top of your suitcase between gates.
