A tool bag should perform some basic functions: First, it should keep your tools where you can easily get to them. Secondly, it should protect them at the job site, on the way to the job site and everywhere in between. And finally, a tool bag should make carrying tools comfortable. But first things first. Like anything thats built to last, VETO PRO PAC tool bags start with a butt-kicking foundation. In this case, its a 3mm thick polypropylene base that is not only waterproof, but drop from the second floor proof. Next we oriented the storage system vertically using interior pockets made of PVC-impregnated 1800 denier, a waterproof nylon that can take whatever a flathead or Phillips head screwdriver can dish out. While VETO PRO PAC tool bags could be considered soft bags they dont wilt and lose their shape like canvas or other synthetic bags. Thats because every PRO PAC tool bag uses a patented integrated center panel that extends to the very bottom of the bag. This allows for easy access and balances your load distribution effectively keeping you from becoming a regular at the chiropractors office. Speaking of pain, the place where your burly hand makes contact with the tool bag is typically where discomfort can put a damper on any quitting time. But we dont do typically too well around here. The handle on VETO PRO PAC tool bags is unlike any youve experienced. Its ergonomically designed for stiff hands and is hinged through the fabric for extra durability. It also collapses front or back depending on how you set it up. Bonus!
