Features of the Fjällräven Kajka
Adjustible to bodymeasures
The backpack has a lot of straps to adjust it to an ergonomic fit.
At first there is the option to adjust the back length. Therefor remove the back plate and pull strap and pull or release the strap to adjust the back length into what fits your size.
The kajka can also be adjusted to fit your exact shoulder width. Use the press studs at the place where the shoulder straps are attached to the bag to adjust it in three different positions; small, medium or large. This way you can create a position that suits you and your body type best.
The kajka has a very broad hip belt to support a good weight distribution. The hip belt also has ventilation holes.
The belt has a system in which the both sides of the belt are pulled towards each other instead of pulling outwards. The advantage that this system gives is that you can pull the belt much tighter. When the hip belt is tightly pulled, it will transfer 75% of the weight of the back onto your hips.
The backpack does also have load-lifter straps to pull the backpack closer to the body to reduce the leverage.
To reduce the leverage of the backpack, the kajka has four compression straps. Two on both sides. This may seem like little and that is also the case but fjällräven used a different technique as which is normally used. On the front of the backpack are two metal bars integrated. One on both sides. These bars run across the entire length of the main compartment. when the compression straps are pulled, the whole bars are pulled towards your back. This reduces the surface of the bag and therefore also the leverage.
Integrated daypack / Detachable lid
The lid of the Kajka can be disconnected from the rest of the backpack to turn it into a small bag that can be used on its own. It can be used as a shoulder bag or as an hip belt. It’s an ideal bag for short day hikes. The bag is too small to carry a bottle so it’s not an option to bring along water in it.
When you want quick access to your top compartment or if you want to divide the weight a bit to your front, you can also choose to remove the top lid from the backpack and attach it to the sternum/breast strap. There are two buckles attached to the front side of your shoulder straps that are meant for attachment.
Hidden in the daypack/lid is an extra small storage compartment where you can put key’s or your wallet in which can come in handy when you want to hide small valuable stuff.
The hip belt is like already said, very broad to support a good weight distribution But this is not all. There are also two extra pockets to put small things into. The left one is made out of a water-repellent material, the right one is made out of webbing.
Ice axe/trekking pole loops
there are two loops at the back to tie your Ice axe or trekking poles up. these can be secured with two Velcro loops.
Water system and bottle storage
The backpack contains two extra side pockets (webbing) for water bottles. These bottles can be placed in an horizontal or a verticale position. Especially the latter is very handy to reach your water while wearing the backpack.
When you have a water system like Camelback or Palatypus it is possible to use a special slack in the main compartment where you can install the water system. The water pipe can leave the backpack from the right corner of the main compartment. From there it can be attached onto a special buckle on the right shoulder strap. When you’re not using a water system, this slack can be used for magazines, books or a small laptop.
FrontloaderThe Fjällraven Kajka is a front loader, this means that you can open up the main compartment from the front. This is a great advantage for it gives you a clear view of what is in your backpack and this makes it easier to put stuff inside in an orderly manner. The compression straps on the backpack are attached to the front loader-flap and therefore don’t fall down on the (dirty) floor, keeping the straps clean.
Ventilated back panel
The backpanel has been specially designed to provide as much ventilation as possible for the back. This contributes to the comfortable use of the backpack.
The sternum strap is adjustable in two directions to the size of your body. In height and in width. On the strap there is also a whistle for emergency situations.
Dry compartmentThe bottom compartment of the kajka has a zipper which allows you to separate or unite this compartment with the main compartment with a water-repellent layer. When this layer is closed you can put wet gear/clothes in this compartment by opening up the outer layer of the backpack and close a mesh-layer. Just connect the two press studs of both layers the outer-layer and mesh-layer) onto each other and the mesh will be pulled into an outward position. Put your wet material in and it will dry on the go.
The dimensions vary to which backpack you buy.
All these backpacks are water-repellent but also have a rain cover included

This backpack is quite heavy when you’re just looking at the specs of it. I must point out that I’ve never had a backpack which felt so light on my back. The very well thought through design makes it feel very light and comfortable on my back.
