The Kilpi RILA 30-U is a practical, handy backpack for hiking and outdoor activities with a volume of 30 liters, which is enough for day trips. The back of the backpack is soft, padded with foam reinforcement and allows air to flow between the back and the backpack. The shoulder straps are shaped and perforated, also for better micro-ventilation. They can be fixed with height-adjustable chest straps, which include a signal whistle, and a padded waist strap with two zippered pockets. The bottom hides an integrated backpack raincoat. On each side you will find a lightweight mesh pocket, a half-liter bottle and an elastic loop for attaching poles. Inside the main compartment there is a pocket for a water bag, with an outlet for a suction hose, and a small zippered pocket for valuables. The other two pockets are located on the front, giving you quick access to their contents. The weight of the Kilpi RILA 30-U backpack is 870g and the back dimensions are 50cm x 25cm. Material composition: 80% nylon, 20% elastane.
