Great idea, needs improvement.

I am an apprentice electrician, and wanted a backpack to pack various tools with me. I was excited to get this backpack, and very pleased with the pockets. I loaded it with tools, and was impressed by how well it held almost everything I needed it to. After taking it into the building I was working in the first day after loading it, I was very sad to find that one of the zippers didn't hold, and pulled apart. The bag was zipped shut, and now wont zip at all, as the entire zipper came undone, all the way around.
