Durability with high functionality and comfort - the Kajka 35 is an advanced trekking daypack praised by hikers around the world. One of the reasons for this is the wooden frame made of birch wood, which, together with the easily adjustable back length, makes Kajka a backpack designed for carrying heavy loads so that you can focus on hiking instead of back pain. Ergonomic shoulder straps and a supportive hip belt with pockets provide even more functionality and comfort. Made of durable Vinylon F material with reinforced fabric made of recycled polyamide. You can add even more storage space to the Kajka 35 by attaching the Kajka side pockets to the side loops; there are also loops at the front for attaching trekking poles/ice axes. The main compartment features an interior mesh pocket and a full front zip opening for easy organization and a great view of your contents. The top cover has three zippered pockets and can be removed and used as a cross body bag. Two compression straps on each side provide even and effective compression, while the side pockets remain accessible. Compatible with a hydration system. Includes rain cover. The S/M models have shoulder straps that are slightly tapered at the front to better fit smaller bodies and provide more room for the chest, as well as a slightly shorter adjustable hip belt. M/L models have longer shoulder straps that don't taper at the ends to better fit wider body types.
