LJK This heavy backpack with external frame was originally designed for paratroopers of the Finnish army in the early 1980s. Capacity approx. 80 l. This backpack, designed for heavy military use, can be used more heavily than most users, such as a free fall of an aircraft. Given its properties, LJK is also suitable for average users and it is an excellent choice for those looking for a lifetime collaboration. The LJK backpack was launched in 1985. Originally designed for military use, the backpack was also warmly welcomed by civilian users. The special features of the model are a frame without the upper curve, which makes moving easier because it does not get in the way of the head. There are no pockets on the sides of the backpack in the lower section, which makes cross-country skiing with the backpack more comfortable. The LJK backpack is still used in the Finnish Armed Forces and is just as popular with recreational users. A traditional backpack with external frame is at its best with a heavy load, but is also suitable for lighter trips. The external tube frame ensures air circulation between the user's pocket and back, significantly reducing the heat load. Although anatomical backpacks have taken over some grass in the backpack market, there are still situations where nothing is better than an external frame backpack. Compartments The upper compartment of the bag (dimensions about 45 x 40 x 20 cm) is closed by attaching the opening of the drawstring, which is secured with a waterproof protective collar that also allows overpackaging. The opening is covered with a generous flap that is secured with straps. The straps are long enough to wear, for example, a sleeping bag or mat under the flap. If necessary, the straps can be easily extended with the included detachable straps. The top and lower pockets of the bag are separated by a built-in distributor. The valve of the upper compartment has a flat compartment for small objects (dimensions about 25 x 45 cm), which are also suitable for larger objects that need to be easily accessible. The exterior of the upper compartment is equipped with a flat card pocket with zipper (dimensions approximately 30 x 30 cm). The lower compartment of the bag (dimensions about 35 x 35 x 20 cm) opens on both vertical sides with a zipper. The zippers are protected with a button closure. The flaps should always be gently fastened, as they take away some of the weight and strain the zippers. The side pockets (dimensions approximately 40 x 10 x 7 cm) are closed by attracting the waterproof protective collar, which is covered with a flap that can be secured with straps. The left side pocket is divided into two compartments with a built-in distributor. The lower compartment is accessible via the zipper on the side. In the lower back there is a large outer compartment (dimensions approximately 32 x 25 x 10 cm) that is closed by tightening the protective collar. The bag is covered with a valve that is fastened with two straps. This bag is ideal for packing items that should be easily accessible during the walk, such as a camping stove and food. OTHER ANCHORAGES There is a generous number of fastening loops on top of the valve and in the main compartment. This makes it possible to secure even large loads (such as the beloved Sissi tent) on or under the valve by means of detachable tires. The loops on the inside of the flap are perfect for attaching a sleeping mat. Especially a military-style tent mattress can be attached to this by means of the elastic bands. Axes or other long, narrow stocks can be transported behind the tunnel-shaped side pockets. The fasteners with straps above the side compartments ensure the attachment of the supplies. The lower corners of the shoulder straps have loops that serve as attachment points for small objects, such as water bottles. SUPPORT SYSTEM The frame of the support system is the strong aluminium tube frame of the LJK model. Unlike civilian backpacks, LJK does not have an upper bend because the bend easily sits in the head when it is necessary to move on rough terrain. Furthermore, the frame of LJK has been reinforced with additional support blocks. The shoulder straps and waistband are firmly padded and anatomically shaped. The buckle of the hip belt can be detached very quickly with one hand. It is a very valuable feature in a possible emergency. The nodded chest strap provides extra comfort and support when wearing. The stepless adjustable (length) support support system and lap belt of the backpack can be adapted to users of all different heights and sizes. It is possible to adjust the center of gravity of the shoulder straps even while walking by tightening and loosening the straps attached to the top of the frame. The centre of gravity of the backpack itself between the shoulders and the hips is adjusted by loosening and tightening the shoulder straps and hip belt.
