Elmont Professional Hiking Backpack Outdoor Travel Durable Mens 50L Capacity Shoulder Bag Womens Walking Bag with Water Bottle Holder

The backpack works really well!

You can use it right away. The color matches the picture, and there are several zippers for storage, like on the top and around the waist. The carrying system takes up some space in the backpack, so the actual capacity might be less than 50L. The backpack itself has some weight, and it feels heavy after packing it (not including camping gear and extra shoes). The carrying system helps a bit but not much, as you can feel the whole backpack sagging and putting pressure on your shoulders. Whether you use the chest and waist buckles or not doesn't make much difference; it's okay for short hikes but not recommended for multi-day heavy-duty hiking trips.
