Lindby Backpack – The Convertible Daypack for Everyday Freedom

Meet the Lindby backpack by Kapten & Son – a smart, convertible urban backpack and tote hybrid built for real-life mobility. With its clean look, compact 12L volume and cleverly designed interior, it’s made for people who juggle work, errands, side projects and mini adventures without changing bags three times a day. Crafted from recycled PET vegan tech material, the Lindby is water-repellent, robust and easy to care for – a minimalist everyday pack that hides a lot more functionality than it lets on.

Who is it for?

Urban commuters, hybrid workers, young parents, creative nomads and anyone who wants a versatile, city-ready backpack that can instantly turn into a tote. If your days swing from office to café to playground to train – sometimes all before lunch – the Kapten & Son Lindby keeps pace: hands-free when you need it, low-profile when you don’t, whether you’re walking, cycling or hopping on a last-minute train.

What Makes It Stand Out

🖐️ Convertible carry (backpack → tote): Padded, adjustable straps for backpack mode that you can tuck away behind the second back layer, plus sturdy top handles for tote mode – switch styles in seconds, no repacking needed.
📐 Optimised 12L city format: A slim silhouette that still fits a full day: laptop, tablet, notebook, lunchbox and daily essentials, without feeling bulky on your back or at your feet in a café.
💻 Made for laptops & tablets: A padded laptop compartment (29.5 x 25 x 2 cm – fits most 14" laptops, including 14" MacBook) plus a dedicated tablet sleeve, so your main devices stay protected, separate and easy to reach.
🧩 Ultra-organised interior: Front zip pocket, inside zip pocket, two open pockets, a flat compartment for a changing mat or extra laptop protection, plus internal and external bottle holders so nothing disappears to the bottom.
🌍 Travel-smart, conscious build: Suitcase attachment on the back, cabin-friendly size and a vegan, recycled PET outer fabric that’s water-repellent and made to handle years of everyday city use.

For work, it comfortably swallows a 14" laptop, tablet, notebook, charger and lunchbox. For parent life, you can swap in nappies, wipes, spare clothes and bottles – the organisation stays the same, only the mission changes. On the move, whether you’re hopping on your bike, rushing for a train or leaving for a spontaneous overnight stay, the Lindby backpack stays close to your back and keeps your essentials exactly where you expect them.

Why You’re Going to Love It

Whether you pack light or tend to carry a few “just in case” extras, the Lindby adapts without turning into a bulky cube on your back. It stays compact, neat and easy to live with – the kind of bag you don’t have to think about.

Switches from backpack to bag in a moment, while your packing and organisation stay exactly the same.
Keeps your day beautifully organised with dedicated spots for laptop, tablet, bottles, small items and on-the-go essentials.
Sits close and low-profile on your back – comfortable in packed metros, narrow streets or busy coffee shop queues.
Handles everyday weather with its water-repellent vegan tech material, ideal for commutes, drizzle and the odd surprise shower.
Easy to clean, built to last and ready to follow you from weekdays to weekends and spontaneous city breaks.

If you’ve been searching for a compact, organised everyday backpack that follows you from laptop days to parent life and cabin trips without sacrificing style, the Lindby quietly ticks all the boxes. Add it to your setup and stop switching bags for every scene – one pack, all your missions.

Love the Kapten & Son aesthetic but sometimes need more space? Take a look at the Bergen Pro – same clean vibe, extra volume for longer days. Prefer a roll-top travel companion instead? The Lisbon backpack is ideal for weekend escapes and one-bag adventures. You can also explore all our Kapten & Son backpacks to find the format that fits your lifestyle best.

FAQ

Does the Lindby fit a 14" laptop?

Yes. The padded laptop compartment measures 29.5 x 25 x 2 cm and fits most 14" laptops, including a 14" MacBook. There is also a separate tablet compartment for an iPad or e-reader, so your main devices stay protected, organised and easy to reach.

Is the Lindby backpack water-repellent enough for daily commutes?

Yes. The outer fabric is made from recycled PET vegan tech material that is water-repellent – perfect for light rain, splashes and everyday commutes by foot or by bike. For heavy downpours or long exposure, we recommend using an additional rain cover for maximum protection.

Is the Lindby accepted as a cabin or personal item on flights?

With its compact 12L format and slim profile, the Lindby backpack easily fits under most plane seats or in overhead compartments. Depending on the airline, it can count as a personal item – simply compare our dimensions (38 x 40 x 13.5 cm) with your airline’s cabin and personal item rules to be sure.

Is 12L enough for daily use?

For most everyday scenarios, yes. The 12L capacity is optimised for a typical day: 14" laptop, tablet, charger, notebook, wallet, keys, a bottle and a few extras (like a light jacket or lunchbox). If you regularly carry bulky gear or pack for several days, a larger model like the Bergen Pro or Lisbon might suit you better.

Can I use the Lindby as a baby or parent bag?

Yes – it’s a great option for active parents who don’t want the look of a traditional diaper bag. The Lindby includes two side bottle holders, two elastic bottle holders inside, plus a dedicated compartment that can hold a changing mat or spare clothes, while still keeping your tech separated and protected.

How does the backpack-to-bag conversion work?

The Lindby comes with padded, adjustable shoulder straps for backpack mode. When you prefer a cleaner, more minimal look, simply tuck the straps behind the second back layer and carry it by the top handles as a tote bag. You don’t need to change how it’s packed – the interior layout stays exactly the same.

Is the Lindby vegan and eco-conscious?

Yes. The Lindby is fully vegan and made from recycled PET materials, offering a durable, easy-care build while lowering its environmental impact compared to conventional synthetic fabrics. It’s a solid choice if you’re looking for a vegan, recycled urban backpack that still looks clean and premium.
