KADVA Vagabundo backpack 40 l blue (FX-KDV-B4C006-BL)
The Vagabundo 40 l model is a technical backpack designed for trekking, camping, and long-distance trips. It combines high functionality with wearing comfort, making it suitable both for mountain trails and weekend excursions. Its lightweight construction, efficient back ventilation, and thoughtful pocket layout are just some of its advantages.
40 l capacity – for multi-day trips
With a capacity of 40 liters, the backpack can hold all the equipment needed for 2–3 days in the field: clothes, food, camping gear, a sleeping bag, or small electronic devices. Thanks to the practical arrangement of the main compartment and pockets, it is possible to pack conveniently and orderly without having to give up important items.
WINDSPIRE PRO carrying system
The advanced WINDSPIRE PRO carrying system is responsible for wearing comfort, based on a mesh spacer that separates the backpack from the back. This solution improves air circulation and significantly reduces sweating during exertion. As a result, even intense trekking on warmer days does not end in discomfort.
Compatibility with hydration system
The Vagabundo 40 l is fully adapted for use with a water bladder. Inside, you will find a dedicated pocket and an outlet for the tube, which facilitates the installation of the hydration system. This allows you to hydrate without having to stop and reach for a bottle – which can be crucial during long ascents or heat.
Hydrophobic material – repels moisture and dirt
The material used to make the KADVA Vagabundo 40 l backpack has hydrophobic properties, meaning it effectively repels water from the fabric surface. This ensures that even during light rain, the contents of the backpack remain dry, and the material itself does not soak, which translates into less weight and greater comfort in damp conditions.
Rain cover – additional protection
The backpack comes with a rain cover that provides an effective barrier against moisture in case of heavy rainfall. It protects the entire backpack – including zippers and seams – from getting wet. This is an invaluable addition during longer trips when changing weather conditions can surprise you at any moment.
Product Details

Flap-type closure + drawstring + zipper
The backpack is secured with a three-stage system: a drawstring, an internal zipper, and a flap with a buckle. This solution ensures the safety of the contents and allows quick access to the main compartment. It is a practical and proven combination of functionality and comfort in trekking conditions.

Tourniquets and compression straps – packing under control
Straps allow you to attach additional equipment, such as a sleeping mat, blanket, or lightweight sleeping bag. The side compression straps enable you to adjust the backpack's volume to the current contents, keeping everything stable and snug. This facilitates transport and minimises the shifting of luggage inside.

Hip belt with pockets
The wide hip belt stabilises the backpack and relieves the shoulders, which is invaluable when carrying heavier loads. Practical zippered pockets are placed on the hip straps, where you can store an energy gel, phone, keys, or other small items you need close at hand.

Chest strap – additional support
The adjustable chest strap stabilises the shoulder straps and prevents them from slipping off the shoulders. It is especially useful during dynamic movement or walking over rough terrain. It positively affects the ergonomics of carrying the backpack and allows for a better fit to the body shape.

Spacious mesh pocket at the front
A large, flexible mesh pocket located at the front of the backpack is ideal for storing handy items such as a rain jacket, poncho, map, or provisions. The mesh material is stretchy and can hold more than it appears, while also providing quick access to the contents.

Reflective elements – greater safety
Reflective details placed on the backpack increase the user's visibility in low light or after dark, which improves safety on the trail and in urban conditions. It is a simple but important solution, especially in limited visibility.

It's great
I recommend
Revelation
Ideal for trips to the mountains, roomy and has all the attributes I expected from a rucksack.
Cool
Comfortable carry system, one of the few that doesn't pinch my neck.
It accommodated things for a weekend camping trip. The phone pocket is a nice idea, but I can't put my phone in it with the waist belt fastened, the material is too tight and there is no room, maybe it will work out. Other than that it's ok
