My highlander washbag comes with a small mirror built in. the washbag is also large enough to double as a first aid kit, although i've never been big on carrying a first aid kit around. A few neurofen and thats about it really!!
Hygeine wise – a bar of soap, a sponge, toothbrush, toothpaste and some razors. I use soap instead of shaving foam for both face and head.
