KADVA Vagabundo backpack 40 l black (FX-KDV-B4C006-BK)
KADVA Vagabundo 40 l Backpack is a technical trekking model designed for multi-day trips, camping, and long hikes. With a capacity of 40 liters and an advanced construction made of lightweight, durable materials, it provides not only enough space for essential gear but also carrying comfort. The backpack is equipped with a range of practical solutions.
40 l capacity – for multi-day outings
The 40-liter capacity allows you to pack a full set of equipment needed for 2–3-day trips outdoors. The backpack can hold clothes, food, camping accessories, a first aid kit, as well as a tent or sleeping bag. Its compact form makes the Vagabundo model neither too heavy nor cumbersome, which significantly enhances comfort during long hours of walking.
WINDSPIRE PRO carrying system
The use of the WINDSPIRE PRO carrying system ensures effective ventilation and comfort during prolonged wear. The distancing mesh separates the user's back from the backpack's back panel, allowing free airflow. This limits excessive sweating and improves comfort even during intense exertion or hot days.
Compatibility with hydration system
The backpack features a special pocket for a hydration bladder and an opening for the tube, allowing the installation of a camelbak system. This is a very useful option during longer hikes when you don’t want to break your pace to reach for a water bottle. Constant hydration affects performance and physical comfort.
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. Thanks to this, even in light rain, the contents of the backpack remain dry, and the material itself does not soak up water, 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 during heavy rainfall. It protects the entire backpack – including zippers and seams – from getting soaked. This is an invaluable accessory during longer trips when changing weather conditions can surprise you at any moment.
Product Details

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 sternum strap stabilises the shoulder straps and prevents them from slipping off the shoulders. It is especially useful during dynamic movement or walking on 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.

Closure type flap + 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.

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
