I'm looking to get a pair of Kevlar jeans, the question is -- all the Kevlar jeans i have seen only have a short (about 6") zip to join the Kevlar jeans to a current jacket, even the RST Kevlar jeans don't have a full zip.

Does anyone know of Kevlar jeans with a 180 degree zip compatible with an RST type zip or have used the RST belt attachment thing to link the belt to the jacket zip?
