I found it very useful to look at the gear other adventure cyclists are packing, but it took more effort to see how much everything would cost. Here I am including a comprehensive list of what I am carrying and how much it cost me. Much of this stuff I already had, and the rest I bought over a period of two years as it came on special. A gear list with associated item values is also useful for insurance purposes.
I hope you will find this useful, and let me know if you have any questions about the items on my list.
