Using the Mission Workshop Fraction Rucksack is a breeze. First, unzip the external and internal compartments to start loading your daily items. You can put your keys, wallet, and small accessories in the stash pockets. For your laptop or tablet, place them gently in the internal zippered pocket. If you choose to use the optional waist belt, fasten it around your waist for better balance and support when carrying the rucksack. When it comes to maintenance, keep it away from sharp objects to prevent tears. If it gets dirty, use a mild soap and water to clean the fabric. Avoid using harsh chemicals as they may damage the waterproof materials. After cleaning, let it dry naturally in a well - ventilated area. Also, make sure not to overstuff the rucksack as it may affect the internal frame sheet and the overall structure.
