This is a seriously roomy tool bag. The main compartment opens wide (19 inches across) so you can fit big tools like drills or saws. It's made from tough 600-denier nylon with reinforced seams and a hard bottom. There are 8 exterior pockets and 6 interior ones, plus loops and pouches to keep all your screwdrivers, pliers, tape measures, and bits organized. The shoulder strap is padded, and there's even a waist belt for heavier loads (holds up to 25 lbs). A zippered security pocket on the outside is good for your phone or keys. When it's empty, you can roll it up to save space. Ideal for electricians, contractors, or DIYers who need to haul a lot of gear to the job site.
