A snug-fitting, slim backpack for running, cycling and hiking. The Gram 15 Rucksack features Haglöfs' Interact suspension system, which is flexible and comfortable with good support. Side compression straps also help to stabilise the load. A separate pocket, accessible from the rear, provides storage for a hydration reservoir with attachment points for different type of bladders. Essentials that need to be accessed quickly can be stored in the side and hipbelt pockets, or attached to the pack using the elastic cords system.
