The carrying strap is for short trips in the area I am camping in. It is also good if I have to grab & run.

Many types of things can be carried in a tube the size that I have made.

My food tube is painted - desert tan

I have a 4" x 1' tube that I carry my cell phone external antenna, misc electronic parts (pigtails) in. I couldn't help myself from adding a "radiation warning sticker" on the outside. It's a warning label we use in regards to electromagnetic radiation around our transceiver antennas (radar & radio) and I have spray painted this tube - pine forest green (or Detroit Diesel Green)

My 3rd tube measures the same as the Food Tube and is also painted desert tan. I am storing T.V. cable parts in it at the moment.
