I made this Camelback bag many years ago. It got a fair amount of use, then I lost it. In unpacking my belongings after moving to the new house, I found it! I like this project because almost every part of it was salvaged from something else. The main body is made out of the same old dacron sail from the Lightning (#13956). I also used it to make the pannier bags in a previous post.
I salvaged the red velcro from a kayak tie-down system for the roof of a car.
The zipper came out of an old worn-out pair of pants.
The main shoulder straps are made from product packaging. The blue straps with the black edges are material scraps from Burley trailers. When you get a Burley trailer in a box from the factory, the wheel dropouts come wrapped in excess fabric scraps. I saved them and I used them in these straps. The Mesh part of the straps I believe came from some SIXSIXONE kneepads that were packaged in a mesh bag. The USPS chest strap was from a free promotional keychain neck strap. The plastic bits and nylon webbing are reused from old worn out bags. I save those too. You should see my collection of old helmet buckles.
The Camelback Unbottle came from the rep. He was selling off old inventory cheap.
I have used this thing a few times since I found it, and I forgot how much I like it. Of course I do enjoy the appropriate nature of having a nautical themed bag to be a vessel for water. Haha.
