WORKPRO Tool Bag, 10" Wide Mouth Utility Tool Bag with Zipper, Heavy Duty Tool Storage Bag, Multipurpose Tool Case Small Tool Bag for Organizer

I’ve been testing the Workpro 10-inch utility bag as a compact catch-all for small kits around the shop and on the road. It’s a simple, zippered, wide-mouth soft case with short grab handles and no internal pockets. That’s the whole proposition—and it’s better at that job than its modest size suggests.

Build and materials

The bag is made from 1680D oxford cloth with tight, even stitching and a heavy liner. In hand, the fabric feels dense and abrasion-resistant rather than glossy or plasticky. It doesn’t have a rigid frame, but the liner adds enough body that the bag isn’t a shapeless pouch either. Water beads on the exterior and wipes away cleanly, which is exactly what I want from a utility bag that lives in a truck or a damp garage. To be clear, the zippers and seams aren’t sealed; it’s water-resistant, not waterproof.

The dual zipper is heavy for the size of the bag, and the pulls are easy to grab with gloves. After several weeks of daily opening/closing, the action is still smooth. The only nit is at the corners: if you zip fast, the sliders can catch where the track curves. Zipping with one hand while pinching the corner into a gentle radius with the other completely avoids that.

Handles are short and stout. They’re not padded, but on a bag this size you’re unlikely to load it so heavy that you’d miss padding. There’s no shoulder strap, which is appropriate given the footprint.

Form factor and opening

Open, the bag measures about 10 x 8 x 4.5 inches. Closed, it’s roughly 10 x 4.3 x 4.5. The difference matters: when zipped, the profile tapers slightly toward the top, so chunky, boxy items that just barely fit when open might press against the zipper when closed. Think of the form factor like a compact doctor’s bag—wide enough to see everything at a glance, but without side walls that lock at 90 degrees. The mouth opens wide and stays open on the bench without needing a third hand, which is the single biggest reason to choose this style.

There are no internal dividers, loops, or pockets. Depending on your preference, that’s either a blank canvas or a missed opportunity. I treated it as the former and brought my own organization (more on that below).

Capacity and what actually fits

This is a small tool bag, and that’s the point. It’s not designed for a 20V drill/driver with a spare battery and a set of hole saws. Here’s what I comfortably fit at different times without the bag sagging or becoming a zipper fight:

• A compact rotary tool with power supply, a small assortment of bits, collets, and safety glasses
• A basic hand toolkit: six screwdrivers, small and medium pliers, wire stripper, adjustable wrench, utility knife, electrical tape, and a compact headlamp
• A car kit: tire pressure gauge, compact ratchet with a few sockets, fuses, zip ties, tape, gloves, and a flashlight
• A detail/cleaning kit: brushes, microfiber cloths, small bottles (4–8 oz) of cleaner, and a squeegee
• A field tech pouch: labeler tape, USB meter, cable tester, crimp tool for low-voltage connectors, patch cords, and a notebook

Heavier, long-handle tools are less happy in here. A full-size framing hammer is awkward. Full-size screwdrivers fit fine, but a set of oversized pry bars or a 12-inch adjustable wrench will make the bag bow. If your primary need is hauling a mix of long and heavy steel, a rigid-sided tote or a larger 14–16 inch bag will be a better match.

In use

The wide mouth pays off every time. I can pop the zippers to the corners, set the bag on a bench, and everything is immediately visible. That beats rummaging through a deep bucket-style bag for small bits or rolling closures that collapse back on your hands. The same opening makes it easy to pack the bag methodically—place larger items on the bottom and along the sides, then drop small containers or pouches in the middle.

Because there are no built-in pockets, I used a handful of small zip pouches and a magnetic tray to keep fasteners and tiny parts in check. With that system, I never wished for sewn-in pockets. If you prefer a place-for-everything interior, you’ll need to bring your own organizers.

The bag is soft-sided, and while the liner helps, it will flex and sag if you load it with dense metal. That’s not a deal-breaker; it’s inherent to a compact, lightweight bag. I cut a thin sheet of plastic (old cutting board stock) to the footprint of the base. Dropping that in stiffened the bottom just enough to keep the bag upright with heavier contents.

Durability and maintenance

So far, the fabric has shrugged off scuffs from concrete and tailgates. The handles haven’t stretched under typical loads. After a few weeks, I don’t see loose threads or seam creep. As mentioned, the zipper is the only component that asks for a little care at the bends. A drop of zipper lubricant (or even beeswax) makes the sliders glide more forgivingly around the corners.

Cleaning is easy: a damp cloth takes off most grime, and the interior liner doesn’t absorb spills readily. If you’re carrying oils or solvents, I’d still store them in secondary containers.

Portability and storage

The size is a sweet spot for tossing into a larger rolling bag, trunk, or tool chest drawer. Closed, it’s thin enough to stack. The handles let you grab and go one-handed without feeling like you’re carrying a lunch pail full of bowling balls. I wouldn’t hang it from a ladder rung loaded with heavy tools, but for light-to-moderate kits, it’s secure.

Where it shines

• Building focused kits. If you want a dedicated rotary-tool bag, a small electronics repair kit, or a glovebox tool set, this is ideal.
• Quick-access bench work. The wide opening makes it a good companion on a work surface where you’re constantly in and out of the bag.
• Multipurpose utility beyond tools. It also works for art supplies, small office gear, or a compact field-first-aid kit. The wipeable exterior makes crossover use practical.

Where it falls short

• Not a drill bag. Most cordless drills with a battery attached are simply too tall and bulky. Even if you can squeeze one in, the zipper taper will fight you.
• Soft-sided sag. Loaded with heavy steel, the bag loses shape. A stiffener helps, but this will never behave like a framed tote.
• No native organization. If you want dedicated pockets and loops, you’ll have to add pouches or inserts.

Tips to get the most from it

• Add a base stiffener. A cut-to-size thin HDPE sheet or trimmed cutting board makes the bottom flatter and the bag more stable.
• Use color-coded pouches. Separate fasteners, bits, and small parts so the big cavity stays tidy.
• Zip with intention. Guide the corners with your off hand and the zippers run smoother and last longer.
• Label the spine. A strip of painter’s tape or a sewn-on patch makes it easy to ID kits when stacked on a shelf.

The bottom line

The Workpro 10-inch bag is a straightforward, well-built small utility case. Its strength is the wide mouth and tough fabric, not brute capacity or built-in organization. If you need to carry a carefully curated set of hand tools, a compact power tool with accessories, or a specialized kit that benefits from quick visibility, this bag does the job cleanly and without fuss. If your day-to-day requires a drill, large drivers, or a hammer and heavy pry bars, you’ll be happier stepping up to a larger, rigid option.

Recommendation: I recommend this bag for anyone building small, focused kits where fast access and portability matter more than hauling power tools. It’s durable for its size, easy to keep clean, and the wide opening makes it more useful than many similar soft cases. Just pair it with a few pouches (and consider a base stiffener) and it becomes a tidy, dependable organizer that earns its keep.
