amazon.com: swissgear work pack laptop backpack for tool storage, fits 14-inch notebook : electronics

I carry around selection of tools and hardware for assembling furniture and mounting TV's artwork mirrors, etc.
The backpack is duty, and stands up well on it's own due to the reinforced molded bottom shell section.
There is plenty of inside for my cordless drill and two battery packs, full size hammer, drill bit case, deep well socket set, stud finders, screw driver set, organizer for screws and anchors, Allen wrench set, book, and lots more.
I sometimes even bring 24 spirit level with me and cinch that in the side pocket, and it has never once fallen out..
The only downsides to the backpack that I've found in using it the couple months are 1.
The overall weight of the bag - I'm getting used to it, and the couple pounds of weight vs the other backpacks I've used is noticeable. 2.
The rigid molded lower section of the backpack which helps it maintain its shape and stand up on its own does not feel great against my lower back when carrying it for long periods. 3.
The front pocket section has lot of loops which would be perfect for pens pencils drill bits etc except none of them are open on the bottom.
I'm not sure or if it's actual design choice, except it just does not work as intended.
You should be able to slot all of the above mentioned items in the front pouch for easy access, and it just does not work the way they have it..
