Lisbon Duffle Backpack Medium - Your All-in-One Carry-On for Effortless Adventures
Ever packed for a trip and wished one bag could do it all? Meet the Lisbon Duffle Backpack Medium by Kapten & Son - where sleek city design meets outdoor freedom. With a generous 50L capacity and 2-in-1 convertible design, this vegan travel backpack moves effortlessly from airport gates to remote cabins. Built from water-repellent recycled PET ripstop with a TPU-coated finish, it’s the kind of modular travel gear that lets you roam light, stay organized, and look good doing it.
Whether you’re flying carry-on only or packing for a long weekend, its balanced format nails the sweet spot between compact adventure pack and carry-on compliant duffle.
Who is it for?
For modern explorers, digital nomads, gym-to-office commuters, and minimalist travelers - anyone chasing freedom, flexibility, and a cleaner way to move. The Lisbon Duffle Backpack Medium keeps up with your rhythm from sunrise flights to spontaneous road trips.


Why It Stands Out
- 💼 2-in-1 Convertible Design (Backpack + Duffle): Switch modes instantly for hand-carry, shoulder, or backpack wear
- 💻 Padded 16" Laptop Compartment: Fleece-lined sleeve keeps your tech protected and accessible
- 💧 Water-Repellent Recycled PET + TPU Coating: Durable, vegan, and weatherproof for on-the-go adventures
- 🧳 50L Volume, Carry-On Friendly: Ideal for 2-4-day escapes, business trips, or minimalist one-bag travel
- 👟 Smart Storage System: Includes shoe bag, laundry pouch, wet pocket, and multiple zip compartments
Why You’ll Love It
- Switches from city mode to travel mode in seconds - versatility at its best
- Keeps gear separated and fresh thanks to the wet pocket & laundry bag
- Comfortable to carry even fully loaded - padded straps, chest strap, and back support
- Perfect balance of structure, capacity, and minimalist design
- Completely vegan, water-repellent, and sustainably made
The Lisbon Duffle Backpack Medium redefines freedom on the move. Slip it under the plane seat, swing it into your coworking space, or toss it in the van for a spontaneous weekend - this bag keeps up with every plan and detour. It’s not just a bag; it’s your eco travel essential built for a life in motion.
Need a smaller, lighter setup? Check out the Lisbon Duffle Backpack Small - same clean design in a 33L format, ideal for daily commutes and overnight stays. Prefer a more urban shape? The Lisbon Pro Backpack delivers the same minimalist aesthetic in a structured daypack format. And if you’re all about hands-free mobility, the Lisbon Crossbody Bag makes the perfect companion for everyday essentials.
