Crumpler tells you right in the name that the Six Hundred Daily XL is "XL" and you should listen: without its removable insert, this bag has internal dimensions of approximately 18x26x40cm; with the insert, you're looking at about 14x24x36cm. It's a messenger-style bag, so if you're planning to fill it up, you better make sure that your shoulder is up to the challenge, or you're 21 and indestructible, whichever applies. It's in excellent condition, with only very minor wear.
