I use a waist pack that I got at Kmart for about $10. It is designed for fishing and has side pockets that hold fly boxes and allow you to access them without having to spin it around. For about $10 you can buy one of these packs and try it out before investing in a more expensive version. I have been happy mine.

Robert, I saw those shirts the other day. They are 100% nylon and they looked like they would be very hot to wear in the summer. Are they hot to wear?
