Tromso Backpack – Compact. Clever. Chaos-Proof.
Commute, café, daycare dash — whatever your day throws at you, the Tromso Backpack by Kapten & Son keeps you streamlined. It’s a minimalist daypack with serious multitasking DNA. Designed in Germany with a sharp Scandinavian aesthetic, Tromso blends clean lines with clever storage in a featherlight 9L format.
Made from water-repellent, vegan tech fabric and lined with recycled PET, it’s an eco-conscious everyday bag built for quick grabs, messy snacks, and remote work setups. From stroller hooks to subway rides, Tromso is your no-fuss, hands-free companion.
✨ Who's it for?
You’re juggling work, errands, or a toddler (sometimes all at once)? You crave compact carry that’s still functional? This is your go-to. Tromso fits a 14” laptop, snacks, water bottle, and those just-in-case items — all without the bulk of a traditional diaper bag or commuter pack.


What Makes It Stand Out
- ✔️ 9L of smart space: Laptop, bottle, wipes, wallet — everything has its spot
- ✔️ Parent-tested features: Hidden anti-theft pocket, buggy strap loops, internal bottle sleeve
- ✔️ Built to brave the elements: Water-resistant exterior + recycled lining
- ✔️ Magnetic flap + zip closure: One-handed access, extra security
- ✔️ All-day comfort: Lightweight build, padded adjustable shoulder straps
Real-Life Use Cases
- Morning rush: Sling it on, grab a bottle, slip your laptop in — out the door in 30 seconds
- Park day with kids: Bottle holder, spare snacks, and baby wipes? Nailed it
- Work-from-anywhere: Set up at a café with everything organized and in reach
The Tromso Backpack isn’t just stylish — it’s strategic. It trims the fat and adds features that make your day flow smoother. Whether you're a design geek, a new parent, or just tired of clunky bags, this one checks every box for compact, functional carry.
