Durability with high functionality and comfort – Kajka 35 is an advanced trekking daypack that has been praised by hikers all over the world. One reason is its wooden frame construction made from birch, which together with the easily adjusted back length, makes Kajka a backpack designed to carry heavy loads so you can focus on hiking rather than back pain. The ergonomic shoulder straps and supportive hip belt with a pocket add even more functionality and comfort. Made from durable Vinylon F fabric with reinforcement fabric in recycled polyamide. Add more storage to Kajka 35 by attaching Kajka Side Pockets to the loops on the sides; there are also loops on the front for attaching hiking poles/ice axes. The main compartment has an internal mesh pocket and full front zipper opening for easy organising and a great overview of contents. The top lid has three zippered pockets and can be detached and used as a crossbody bag. Two compression straps on each side provide even and effective compression while leaving the side pockets accessible. Hydration system compatible. Rain cover included. S/M models have slightly tapered shoulder straps at the front to better fit smaller frames and give more room for the bust, plus a slightly shorter adjustable hipbelt. M/L models have longer shoulder straps that do not taper at the ends to better fit wider torsos.

Frequently Asked Questions

The ideal backpack capacity for a 2 days 1 night trip will be between 30L - 40L, whereas a 3 days 2 nights trip will be between 40L - 50L. If you are going for trips with colder climates, it is recommended to bring a backpack of between 45L - 65L for space allowance for your winter apparels and gears.
The hip belt should fit near the top on the upper part of your hips, and the shoulder straps should contour over your shoulders, ensuring there are no gaps.
The 20% rule is a foundational guideline that your multi-day trekking backpack should never exceed 20% of your body weight. Exceeding 20% of your body weight places strain on your knees, lower back, and feet which affects your balance on uneven terrain and tires you out easily.
The wooden frame is a structural support system that distributes weight to the hips and prevents the pack from sagging while on the go.
They keep the bag centered on your back, which prevents the backpack from shifting while running, hiking, or engaging in outdoor activities.
They provide extra storage and are perfect for holding irregular shaped items that don't easily fit inside your main compartment, such as sleeping bags, or rain jackets.
Wider, padded straps evenly distributes the weight over a larger surface area, making a heavily packed bag feel noticeably lighter.
