The Patch Field Strips from TAREINCO look like handy little buggers. They are strips of webbing with loop material sewn on them that can be secured in a column of PALS webbing. You can place several of them together to create as large or as small of a patch panel as you need. In addition to serving as patch panels, these would also be excellent for placing on the lower front of a plate carrier to make it compatible with chest rigs like those from Mayflower R&C or Extreme Gear Labs.
The Patch Field Strips are sold in packs of two. Check them out at TAREINCO.
