This tactical backpack is made of high density oxford fabric, which is light weight, durable, and wear resistant. Ventilated mesh padding in the back area and at the top of the shoulder straps make this pack very comfortable to wear, even when it is full. This pack has two large main compartments, with an additional two small compartments in the front. There are d-rings throughout the backpack, allowing for attachments. Two straps located at the bottom of the backpack can be used to hold a sleeping bag, mat, or tent. The tactical molle system allows for addon pouches to be attached to the outside of this backpack.
