The Abisko series from Fjällräven is designed for forest trails and mountainous terrains. This 48liter backpack is suitable for weekend trips if using somewhat traditional equipment, and closer to a week long excursions with lightweight gear. The fabrics are made from recycled fibers. The 210-denier main fabric provides excellent durability, while the reinforced bottom is made of 500-denier polyamide. As with many backpacks, the fabric is water-resistant, so there's no immediate need to use the included rain cover during light showers. The Abisko Trek is a durable and stylish backpack, true to Fjällrävens classic aesthetic, and a reliable companion for hiking trails. - M/L size: for average and larger bodies, adjustable back panel fits torso lengths between 39 cm and 51 cm - Hip belt adjusts up to 150 cm - (Torso length is measured from the most prominent neck vertebra to the top of the hip bone) - Access to the main compartment from the top, front panel, and lower zipper
