Good rucksack. one large storage space inside, and two smaller pockets inside the hood cover. Also has tubing for a bladder (a hole as well as a clip down the shoulder strap) and the bladder itself prbably fits into the sleeve inside the main compartment. Only had it for a week but seems solidly constructed, too
Downside is that the straps are a bit tiny and whimsical. the waist strap in particular is on the narrow side, and it is also a bit short (I am a man, with a waist size 38", and the strap is just about long enough to wrap around me, but only right on the shirt, never on top of a jacket or similar.
