Hiking backpack KADVA Londer 25 l black (KDV-B5C036-BK)
KADVA Londer 25 l is a versatile backpack designed for urban and travel use, featuring a modern closure system. It is perfect for everyday activities such as commuting or hiking, offering comfortable and well-thought-out solutions. Thanks to the roll-top closure, the user can easily adjust its volume according to current needs, and the functional design makes it easy to organise and carry all the essentials.
Laptop pocket and functional interior
The backpack includes a separate compartment designed for a laptop up to 16 inches. The pocket inside the main compartment allows safe transport of the electronic device, keeping it separate from the rest of the luggage. An additional internal pocket enables organisation of small accessories, improving everyday usability.
Combination of synthetic materials with a lightweight structure
The backpack is made from a fabric combining polyamide and polyester fibres, which provides good mechanical resistance and low weight. The outer material is based on fibres with increased durability, while the interior is lined with polyester fibre lining, which handles moisture well and dries quickly. This combination makes the backpack suitable for variable weather conditions.
Roll-top closure with buckle for flexible capacity
KADVA Londer 25 l uses a closure system based on rolling the top part of the backpack and securing it with a buckle. This solution allows adjustment of the backpack’s volume depending on the load. The flap, once rolled, is additionally fastened with a clip that enhances the seal of the construction and increases the security of the carried items.
Urban and travel applications
KADVA Londer 25 l combines practical features with the aesthetics of an everyday urban backpack. Its lightweight form and compact dimensions make it suitable both for walking trips and commuting to work or school. The travel-oriented design features increase its versatility and allow easy use in various conditions.
Additional features and hydrophobic material
KADVA Londer 25 l is made from a material with hydrophobic properties, which limits moisture absorption by the backpack’s surface. The closure method protects the contents from atmospheric precipitation. All these features make the model meet the expectations of users looking for a lightweight, versatile backpack adapted to diverse activities.

Product Details

Closure reinforcing clips
After rolling up the top part, the structure is secured with an additional clip. This increases the tightness and protection against accidental opening. It is a practical element that enhances the safety of the contents.

Internal pocket for a 16" laptop

Inner pocket for small items
In the main compartment, there is a smaller pocket. It makes it easier to store accessories that should be at hand. It’s a good place for documents, a charger, or keys.

Construction without a hip belt
The model does not have a hip belt, which simplifies its design. As a result, it is lighter and more mobile. It works well in situations where distributing weight to the hips is not necessary.

Rolled closure with a buckle
The main chamber is closed by rolling the material. The flap is secured with a sturdy buckle that prevents it from opening. This solution allows for flexible adjustment of the capacity to meet needs.

Hydrophobic material on the surface
The outer fabric of the backpack is hydrophobic. This limits water absorption and improves the protection of the contents. The material withstands weather conditions well.
