Using this backpack is a breeze. First, pack your sleeping bag in the separate compartment at the bottom. Then, load your main items into the top - loading main compartment. You can store small, frequently - used items in the dual - zippered hip pockets. Attach your ice axes and trekking poles to the designated points when needed. Remember to adjust the continuous - wrap harness and hipbelt for a comfortable fit. When it comes to maintenance, clean the backpack regularly with a mild detergent and warm water. Let it dry thoroughly before storing. Avoid overloading the backpack beyond its max carry weight of 15.9 kg / 35 lbs to ensure its longevity and your comfort during adventures.
