Our tool roll-up pouch organizer is made with the same attention to detail we put into all our tools. This starts with the choice of materials. We use durable polyester canvas for the body and reinforced clear fabric for the pocket window. In addition, the whole bag is coated with poly-urethane to provide extra water resistance and flexibility.Materials are only half the picture, though. Superior construction makes this tool organizer last as long as your project list. Seams are double stitched and every tool slot is reinforced with extra stitching to ensure that the 10478 can endure anything you put it through, while keeping your tools safe. Smart design features include a durable pull strap on the inside pouch’s zipper for convenience when you’re wearing gloves or in a rush. To ensure a stable closure, we’ve used anodized steel hooks to fasten the straps.
