What's in your FAT Backpack?

I have ridden with folks that take nothing but an allen key and a bottle of water, while others could rebuild their bike with spare parts on the trail in the dark.  I try to keep my backpack towards the lighter end of the spectrum.   

I carry the vast majority of my tools in this inexpensive two compartment pencil case.  As this is the heaviest item it lays on the bottom of my fatpack. 



The case is jam packed full of items that I would need to get me (or a buddy) back on the trail if something should go wrong.

Clockwise from top left:

- Tire levers
- Two quick links
- Needle nose plyers
- Utility knike
- Various zip ties
- Matches
- Electrical tape
- Patch kit
- Multi-tool (center)

I also carry a small high volume pump, tire gauge, tube and a pair of stretchy gloves.  The folding saw gets added if I'm riding after a large wind storm or if I'm riding in unfamiliar wooded terrain.

Its always good to bring along food in case you or a buddy get low on fuel. Taste of Nature and Clif bars are my favorite, with a few boxes of raisins for a quick boost of energy.

A fatpack would not be complete without a few medical supplies.  A couple of large band-aids, lip balm (mostly for winter), sun screen (mostly for summer) and arnica (homeopathic used for impact injuries).

The food and medical supplies are in double plastic ziplock type bags to keep it dry.  I also squirrel away a $5 bill in case a convenience store stop is needed.  And finally, attached to the outside of the pack, is a waterproof watch and Fox 40 whistle.

Although additional things do creep in from time to time, based on the excursion, I feel the above items are the bare necessities for my fatbike adventures.  

Is there anything you would add or remove?
