Re: Important stuff!
A high quality water filter - I use a Katadyn (PUR) Hiker. A MSR Miniworks is good, too.
Water purification tablets - These have a shelf life, so they need to be replaced periodically.
Something to start a fire - Waterproof matches, lighter, different types of fire starters.
If you have inflatable PFDs, spare CO2 cartridges are recommended.
Toilet paper - Hey nature calls!
Duct tape - It does wonders.
Edit - This is a good thread.
