Tajima SFKBN-KG3L Detachable Waist Pouch & Nail Bag - 3-Tier Large Capacity Tool Organizer for Construction, Carpentry & DIY Projects (Japan Import)

The best modular tool belt system. Hard to find in the US, but worth the effort. This is a huge pouch, you'll need a harness if you plan on loading it to the max. I can't describe what the material is, but it's tough. I haven't been gentle on this, and it's held up great. the clip system is compatible with Tajima measuring tapes.Pay the extra money and invest in good quality.
