After my first prototype, I adjusted the pattern to better fit my body. If you want more information about the materials used and where on the pack, check out my previous post.
The significant changes occurred at the top of the back piece. First, I widened the back piece from 11-1/2 to 13-1/2 inches. Second, I flattened the middle portion of the top back seam and changed the slope of the side portions to better match the slope of my shoulders. Finally, I also widened the front piece, which means I needed to widen the front top and bottom as well.
I was able to use a lot of materials left over from my first prototype because of the quantity I was required to order. I had excess webbing, tension locks, shock cord, cord locks, 3D spacer mesh, spandura, and grommets. This type of project is still expensive, regardless.
- The length of the pack is too long and rubs against my tailbone area. I will be shortening the pack a bit.
- The width of the pack at the bottom is too wide. I needed to widen the back for my straps, but I’m going to make the front narrow again, and I’m also going to narrow the back bottom.
- The roll top has too much fabric, so that will get shortened. I only need to roll the pack top 3-4 times.
- The sides are also too wide, and I can narrow them and still fit a 1L Nalgene bottle.
- The final pack will be closer to 25L and not 30L.
