Thanks for all of the suggestions and alternative options. I ended up getting the Seattle Sports dry bags from REI, except I picked the large instead of the medium. Why? Because the bags look like they will be a near-perfect fit for the FreeRadical sidebags on my Xtracycle, my tour is going to be 4,500 miles so I need something that will last, and I really don't want to risk my stuff getting wet while I'm riding or camping in the middle of nowhere. =)
