A friend of mine used a fanny pack for all of his multi-hour day rides, he did not want to have a rack on his Trek 520.
I however do not want to wear any packs on a bike. I did White Rim trail several years ago with several friends that all wore backpacks. I however had a small Carradice saddle bag and handlebar bag on my bke. This was a truck supported trip where all we had to carry each day was our water and lunch.
I have friends that do not even want to have a pump on their bike, they carry a small pump in a jersey pocket.
Hiking, cross country skiing, snowshoeing, fanny pack is the way I prefer. We all have our eccentricities.
Tourist, he mentioned that he has used this bike with two small rear panniers, so he's got that covered.

Oops, missed that. Thanks.
