The Carhartt Onsite bag is built for those who need a storage solution that can handle the rigors of heavy home renovation. It uses a very high-density 1200-denier polyester, which is significantly thicker than standard bags and provides excellent resistance to tears and abrasions. The exterior is treated with a specialized coating that helps water bead off the surface, keeping the contents dry during a quick dash from the car to the house in the rain.
The bag's foundation is a molded base that allows it to sit in shallow standing water without any moisture reaching your tools. It also features an internal metal frame that prevents the bag from collapsing or "pancaking" when it's empty, making it much easier to load and unload. Because the fabric and base are so robust, the bag itself has a bit more weight than lighter models, which contributes to its overall stability.
Storage Capacity and Care
With an 18-inch length, this bag is sized for larger power tools and organizers. While it has several internal pockets, they are designed with a tighter fit; they work best for standard drivers and pliers rather than tools with very thick, oversized grips. To keep the heavy-duty zippers moving smoothly in dusty environments, a simple cleaning and occasional lubrication of the tracks is recommended.
- Triple-needle stitching at stress points to handle heavy weights.
- Molded base provides a physical barrier against punctures from sharp tools inside.
- Internal frame maintains the bag's shape for easier tool access.
