The Harkila Fenja backpack is made of nylon with a water-repellent PU coating. Thanks to the rip-stop weave, the fabric is very durable and lightweight. Harnesses are wide, softened, adjustable in height. Additional straps are provided in the chest and lumbar areas - for even weight distribution. The back is semi-rigid, softening pillows are large, thanks to the mesh they pass air well and remove excess moisture from the user's back. Plastic fastexes. The 80-litre main compartment has a small zippered document pocket. There are three external patch pockets: two side and one front. The side ones are fastened with Velcro, the front one with a zipper - and, like the inner one, a YKK-type lock with an additional rubberized lining that prevents the penetration of water. Three straps on the sides can adjust the volume of the central compartment and serve to secure additional equipment, such as a small tent. The Fenja backpack from Harkila is designed for hiking and hunting for up to three days.
