When you change from soil to concrete, Borealis Classic doesn't need to change bags. It has 29 liters of space, enough for extra hiking clothing and a boxed lunch, or fitness necessities, books, and a dedicated pocket for your laptop. Belts and chest straps provide extra comfort when hiking with heavy loads, but you can put them away or remove them while commuting. No matter where you walk, a padded air mesh back panel and foam shoulder straps ensure that your Borealis Classic is extremely comfortable. Don't forget to have a storage bag and two water bottle bags and an auxiliary compartment in front.
