Advantages of this backpack: 1. Make it easy and comfortable for you to carry your essential items. 2. To protect these items from theft, physical damage and weather. 3. To keep your items organized and easily accessible whenever you need to take them out. 4. To withstand the wear of life on the road. Volume/capacity - This is one of the most important variants to consider when choosing a backpack. Designed for hiking and trekking and not for travel. Laptop Sleeve - A laptop case is important for many travelers, not only for shock and liquid spill protection, but also for organization, so make sure the backpack you choose has one if you pick up a laptop. The case will keep your laptop separate from other items in the bag for easy access. Compartments & Pockets - A backpack with multiple compartments and quick access front pockets is useful for organizing your items but don't use the small outer compartments for valuables if fishing is a concern. Elastic outer side pockets: designed to hold water bottles or water pockets. They are a useful feature to look at as you will often want to keep a bottle of water outside your bag for easy access when going out in hot weather or when taking a day hiking.
