The Borealis Classic removes the need to switch bags when you swap dirt for concrete. With 29 litres of space, it's roomy enough for extra hiking layers and a packed lunch, or gym essentials, books and - in a dedicated pocket - your laptop. The hip belt and sternum strap offer extra comfort when hiking with a heavy load, but you can stow or remove them when commuting. And a padded, air-mesh back panel and foam straps ensure the Borealis Classic is comfortable wherever you're walking. Let's not forget a front stash pocket and two water bottle pockets and a secondary compartment - you can't say we didn't give you enough organisation options.Volume: 29 LitresFabric: 420D Nylon, 600D Polyester Print, 300D Mini-Ripstop, 1680D Ballistics NylonLaptop Sleeve: 34.2cm X 26.6cmAverage Weight: 1166g
