KADVA Sendero trekking backpack 35 l black (FX-KDV-B4C003-BK)
KADVA Sendero is a backpack designed for longer outdoor trips – perfect for multi-day trekking, hiking, and camping. With a capacity of 35 liters, it offers enough space for essential gear while maintaining a compact form and comfortable wear. Its construction is based on lightweight yet durable materials, making it a great choice for those who value functionality and technical solutions.
WINDSPIRE carrying system – efficient ventilation and lightness
The WINDSPIRE carrying system used in the backpack is based on a spacer mesh that separates the back of the backpack from the user's back, allowing free airflow. This is the most efficient form of ventilation in trekking backpacks – it reduces sweating, increases comfort on hot days, and helps keep dryness even during intense walking.
Space organization – practical solutions
Sendero offers a well-thought-out interior design that facilitates packing and access to gear. The main compartment with a capacity of 35 liters can hold everything necessary for a multi-day trek. On the front, there is a large pocket with elastic access, ideal for a jacket, map, or other items. Inside the backpack, there is an additional mesh zippered pocket, which serves as a secure place for documents, phone, or small accessories.
Compatibility with a hydration bladder
Sendero 35 l features a dedicated pocket for a hydration bladder and special holders for the tube, spaced every 10 cm. This system allows constant hydration without the need to reach for a bottle – which is especially useful on ascents, long distances, and in hot conditions.
Material with hydrophobic finish
The backpack is made of wear-resistant polyester with hydrophobic properties – effectively repelling water and preventing quick soaking. It works great in light rain and humid conditions, and in case of heavier precipitation, the included rain cover comes to the rescue.
Easy cleaning – without unnecessary complications
The material does not require specialized care – in case of dirt, warm water and a mild detergent are enough to restore its fresh appearance. This is a practical solution for people who often move in changing terrain conditions.
Product Details

Loops for additional equipment
The lower straps allow you to easily attach additional equipment – for example, a sleeping mat, a lightweight sleeping bag, a picnic blanket, or a spare jacket. This is an excellent solution when you need to increase the functionality of the backpack without taking up space in the main compartment. On the front, there is also space for trekking poles.

Chest strap – better fit and stability
The adjustable chest strap with a whistle helps stabilise the backpack on the shoulders, especially during dynamic walking or hiking on uneven terrain. It prevents the straps from slipping, and the weight is distributed evenly, which increases wearing comfort and improves control over the backpack.

Hip belt with pockets – functionality and comfort
The wide hip belt relieves the shoulders by transferring some of the weight to the hips and improving the overall stability of the backpack. Built-in pockets allow quick access to handy small items – such as snacks, documents, a map, or a compass – without the need to take off the backpack.

Ability to attach a lamp
On the front of the backpack, there is a special place to attach an LED light, similar to bicycle models. This simple but effective solution increases visibility after dark – particularly useful in urban conditions, on the trail, or on the way to the shelter.

Reflective elements – better visibility
Additional reflective details increase your safety after dark and in low visibility. Thanks to them, you are more visible to other trail users, cyclists, or vehicles – without the need to wear separate reflectors.

3-in-1 closure – flap, drawstring, and zipper
The backpack is secured in a three-step manner: with a drawstring, a flap, and a zipper. This not only enhances the safety of the items being carried but also protects the contents from rain and dust. This system also allows for convenient access to the interior.

Very comfortable and distributes weight well.
Back finally dry while hiking! I'm petite, my companion is fatter, we swapped backpacks and each of us was comfortable :) I think I'll end up buying a second one.
