The actual bag of the Jääkäri XL (height 84 [max. with rolltop 112 cm] x 32 x 23 cm) has been designed to be slim but still spacious enough to hold the necessary supplies even for a longer hike. The opening of the bag is closed with the dry bag-style rolltop. Rolltop is easy to use even when wearing mittens and the design is practically waterproofed. When open, the rolltop makes packing easy. Once the bag is packed, it rolls easily and fits tight and snugly to the size of the content. With rolltop, the size of the rucksack can be anything between 80 and 100 litres, and the package is always firm!
The opening is covered with a flap which hugs the top of the backpack and is secured with straps. The flap has been attached with adjustable straps from both sides. This “floating” flap enables easy overpacking and the protection of the overpacked load. If necessary, the generous length of the straps provides a lot of space under the flap for extra supplies, such as a sleeping bag. Furthermore, there is a spacious zippered pocket (5 litres, 33 x 31 cm) for valuables inside the flap.
The bag contains a divider with which it can be divided into top and bottom sections. In the top section inside the bag, there is a pocket (35 x 30 cm) for a hydration bladder or supplies to be kept separately. This pocket will easily hold a contemporary 13.3-inch laptop or any smaller pads. In the middle at the lower section of the rolltop there is a protected exit for a hydration bladder hose, cable or antenna.
The contents of the bottom part of the bag can be accessed quickly through a zippered flap (flap dimensions 34 x 34 cm). The zipper has two pullers so the flap can be opened from your preferred spot. The back of the bottom part of the bag has adjustable elastic bands (2 pcs) with quick-release fasteners for tying gear. Additionally, the bottom part flap has four mesh pockets (13 x 13 cm) for storing loose objects and valuables.
With the four compression straps on the sides of the rucksack, the bag can be tightened compactly even if it is not full. The compression straps have been equipped with quick-release fasteners and they can be detached as well as freely adjusted with shortener buckles. The manually welded DUR aluminium support frame is attached to the supportive carrying system with MOLLE loops. This means that the carrying device can be adjusted to accept, for example, a weapon bag between the frame backpack and the frame.
Low on the sides there are open pockets with elasticised openings where you can place small supplies or, alternatively, a long tool or a water bottle, the neck of which can be tied firmly in place with a side compression strap. The bottoms of these pockets also have metal rings to remove water from the pocket.
