This is a well-made small pack. As reviewers here say, it is suited to school and college kit, and would be excellent as a small overnight or flight bag, providing space and protection for a laptop or a camera kit.
However, I bought it as a military style, 50 Litre backpack, capable of carrying significant weight and fully integrated with the MOLLE system. I intended it for short summer trips including significant walking, at least 20 miles per day. The size is about 30L, to be generous; the harness and waist belt are far short of military reqirements for comfortable weight carrying; there is no chest strap; and the MOLLE strips are mostly decorative. For example, The side strips have only three openings and only the middle one is sufficiently wide to take standard straps. This limits attachments to tiny knife sheaths and the like. A couple of small pouches could be added to the back of the pack, but the harness will discourage putting significant additional weight there.
It is a nice pack, and in black, quite elegant, so I will pass it on to my wife who will almost certainly find it useful. However, how long will people keep advertising this as a 50L? - or is this just a brand name?
