If you want to make your own G4, there is a Yahoo Group specifically designed to help you do that. You can find them at this link. Join in on the conversation and go old school on the cheap. Although we no longer have patterns or instructions available to do this, you can find them at Quest Outfitters at this link. Good luck with your project! Of course if you are not a do-it-yourselfer, we still sell the packs and it is our best deal and easiest way to get into backpacking the ultralight way!
