KADVA Companion 20 l city backpack black (FX-KDV-B4C007-BK)
KADVA Companion urban backpack with a capacity of 20 liters is a versatile model that works great both for everyday use and short trips. It combines a modern, minimalist look with practical features that enhance carrying comfort and luggage organization. Thanks to its compact dimensions, it is suitable for the city, university, work, as well as for day trips or as carry-on luggage for a plane.
Ready for travel – carry-on luggage on budget airlines
KADVA Companion 20 l is the perfect travel companion for budget airlines. The rolled-up rolltop meets strict carry-on luggage limits (e.g., Ryanair, Wizz Air), but after security, you can unroll it and gain extra space. No more dressing in layers or stuffing clothes into pockets.
- Rolled up = fits within carry-on luggage limits
- Unrolled = more space after security check
- You save on excess baggage fees
- Ideal for a jacket, sweatshirt, extra layer
- Looks simple, works smart
One backpack, two modes – no hassle, no stress, no extra fees.
Optimized capacity
20 liters is the perfect compromise between compactness and functionality. The backpack fits the essentials: documents, electronics, snacks, clothing, or a lunchbox, while not overwhelming with its volume. It works perfectly for everyday urban conditions but can also handle light outdoor activities.
Roll-top – flexibility and security
The rolltop allows for volume increase when needed, while better protecting the contents from third-party access and light rain. The backpack closes with a zipper and a strap with a buckle, and an additional magnet helps with easy rolling and securing the closure. This solution makes the Companion as flexible as your plans.
Dedicated 15” laptop pocket
The inner compartment is equipped with a divider for a laptop up to 15 inches. The reinforced structure prevents the device from shifting and protects it from damage during transport. It’s a practical choice for students, office workers, or remote workers who always carry their computer with them.
Durable and easy-care material
Made of durable polyester, the Companion backpack is ready for everyday use. The material is characterized by good resistance to abrasion, moisture, and dirt, and its care is exceptionally simple – just a damp cloth and mild detergent. It performs well in changing urban and tourist conditions.
Product Details

Chest strap – greater stability
The adjustable chest strap allows for better stabilisation of the backpack on the back and prevents the shoulder straps from slipping during movement. It is especially useful during faster walking, cycling, or longer strolls. It is an important element that improves ergonomics and wearing comfort.

Pockets – practical placement
At the front of the backpack, there is a spacious zippered pocket, perfect for essential items – phone, documents, wallet, or keys. On the sides, there are elastic pockets for water bottles or other small accessories that you always want to have at hand.

Carrying handle
At the top of the backpack, there is a sturdy handle that allows you to carry it comfortably by hand or hang it on a hook. This practical solution is useful in the office, at home, or on public transport. It also allows you to safely put the backpack down without the risk of it getting dirty.

Reflective elements – visibility after dark
Thanks to reflective details, the backpack increases the user's visibility after dark or in conditions of limited visibility. This is an important feature during autumn walks, evening bike rides, or urban strolls. User safety is a priority – even in an everyday backpack.

Adjustable braces – personalised fit
The KADVA Companion 20 l backpack is equipped with soft, comfortable straps with the possibility of smooth length adjustment. This allows it to be perfectly adapted to the user's height and preferences, which increases wearing comfort – both during daily walks and longer activities.

Roll-up closure – flexibility and style
The modern roll-top closure allows you to adjust the backpack's capacity to the amount of items, while protecting them from rain and dust. It is a practical and stylish solution that emphasises the urban character of the Companion model.
