NOT 40 Liters

Very, very disappointed with this product. It claims to be a 40 liter backpack, but it's no bigger then my 25 liter backpack. Truly falsely advertised by this seller .. The product itself, very cheaply made. Looks cheap. Feels cheap. Constructed cheaply. Not worth the price paid. What You See Is What You Get. There are no pockets or inside secret compartments unlike my other bag. So, you can not store pens or small items inside the bag unless you want to fish at the bottom of the bag for them later.
I bought this bag to up-size what I already have, but it being the same size, I'm going to try and return it for a refund
