The Vaude Aquarius bladder supplied with this pack comes with its own cleaning brush and some oddly IKEA-esque DIY instructions for assembly.
It slides neatly into a zipped sleeve at the back of the slender pack, while another full-length zip pocket with an extra mesh pouch does a grand job of providing sensibly minimal storage space. The soft and thickly padded waist belt and lightly wired back system do a truly great job of transmitting the load to the hips where it belongs, giving this pack a really airy, barely-there feel. Bright canary yellow might not be for everyone though, so other colours are available.
