This innovative, solidly-built Modular Tote is by ToughBuilt. Aimed at tradespeople, it's an open-top tool bag with no less than 68 pockets and loops.It comes with two removable, zippered soft-sided bags and three removable, pocket-laden dividers that can be slotted within ribs in the bag's sidewalls. A nice little UX touch: One of the dividers has a kickstand.The bag is offered in 12", 18" and 30" lengths, the latter being the one pictured above. Here's a video showing the bag's features, in this case the 18" model:For those who ply their trades in the Pacific Northwest, New England or other places where you're traveling through inclement weather to get to the jobsite, the company also offers a closed-top bag called the Massive Mouth. This, too, has a design innovation (patent pending), which is what the bag was named for. The top can be pulled open to the full width of the bag, providing visibility and access. Both bags draw rave reviews for both their build quality and ability to swallow tools.
