lightweight tactical easily concealed assault pack backpack

【How to choose the backpack capacity】
If the travel time is short (1-3 days), and you do not plan to camp outdoors and carry few items, you should choose a backpack with a small volume, generally 25 to 45 liters is enough. This kind of backpack is usually relatively simple in structure, with no or less external hangings. In addition to one main bag, there are usually 3-5 additional bags, which are convenient for sorting and loading items.

If you travel for a long time (more than 3 days) or you need to bring camping equipment, you need to choose a large bag, preferably more than 50 liters. If you need to load a lot of items or a large volume, you can choose an oversized backpack of 75 liters or more or a backpack with more external attachments.
