It's a cheap ripoff of the similar model from maxpedition.
I had one for about 6 months now the lining on the main strap has come off, and the lighter material that is used to make the pockets inside also have started to fall apart. I paid $18 6 months ago and used it every day
To be fair I saw the same wear with maxpedition bags as well but at 4X the cost. It is only the lining on the main strap and the front pocket divider which I plan to repair. The main body shows no signs of damage or severe wear, for $18 it has held up very well I used it every single day for 6 months straight. RedRock offers a version of the maxpedition sitka for under $40 which I ordered. Having owned a few maxpedition products I wasnt very impressed.
