Awesome! Feels great to get that first one under your belt, doesn't it? Made my first one a couple years ago, took it on a bp trip down the Grand Canyon. I was impressed by how well it handled, then found changes I wanted, which led to my second version. Been using that one for a couple years now, but have to admit I am thinking of more changes for a third version.

I love your color choices, and the finished pack looks real professional (mine definitely looks homemade). I would be interested in more on how you added a zipper. I had thought of that a couple times, but wasn't sure how to add a zipper. The ones I've found were of a size that didn't work with my pack.
Life should not be a journey to the grave with the intent of arriving safely in a well preserved body, but to skid in broadside, thoroughly used up, worn out, and loudly proclaiming Wow! What a Ride!
