Adventure Cycling and America ByCycle have created this fun and useful video on packing your panniers for a tour. I do have one contribution to the content of this video. After a few tours spent rummaging through panniers looking for that pair of cozy socks or that clean t-shirt, I came up with a simple method to help me find clothing quickly. I keep clothes that go above the waist in one pannier (the right rear pannier to be precise) and clothes that go below the waist in another. Of course, using multiple stuff sacks as shown in the video may render this technique unnecessary.
