The bag itself is nothing less than great. Just, it’s small. The main space, also, is divided into 2 parts by a thick separator. Many many pockets and rock solid, this bag is incredibly good. The are only 2 big defeats: 1) it should be larger. With the class D amps, a bassist/guitarists would like a backpack like this to carry all he needs; 2) the separator should be detachable. At times it is good to have one, others you need the full space and that layer is thick enough to steal lots of space.
I strongly believe that an XL version, 10 cm larger and with detachable separator, priced at 42,90-44,90, would less lots of units as it would solve problems that this can’t solve due to its tightness
