• LARGE CAPACITY & LIGHTWEIGHT: The Rock Series Backpacks have two capacities available: 40 5L and 60 5L, which meet most people's needs. For every hiker, every gram counts so we focus on providing lightweight camping gear. Our 40 5L backpack is only 2.73lbs, 60 5L backpack is only 2.93lbs, making your hiking trips more enjoyable.
• HIGH-QUALITY FABRIC: These mountaineering rucksacks are made of high-quality 420D nylon for durability and scratch resistance. They are water repellent, which means not completely waterproof, so we have a rain cover inside the bottom pocket in case you catch a sudden rain while hiking.
• ERGONOMIC DESIGN: Ergonomically designed back pad and thick shoulder pad scientifically reduce back pressure. The back pad has a mesh structure breathable and comfortable even if you carry a backpack for a long time you will not feel tired.
• MULTI-POCKETS & DIY WINDROPE SYSTEM: Our backpacks have multiple pockets to store lots of camping gear. A large open mesh pocket on the back of the backpack allows you to quickly access and store stuff. If you need extra space, you can also bind things such as trekking poles or sleeping bags firmly with compression straps on the top and both sides of the backpack.
