I just wanted to share a great idea, that came to us courtesy of Ray (biketouringtips.com), who also posts here. We had the pleasure of meeting Ray and his wife recently and they gave us the materials to make the cyclist's tea cozy, out of heating duct insulation and velcro:
It helps you keep your tea warm, and you can cook pasta faster by just boiling the water, putting the pasta in and taking it off the burner and covering for a few minutes. It also doubles as a cool bag to keep things better in hot weather.
Brilliant! Thanks Ray
