CROW 2" wide 4 pt harness, I have seen people killed at work who were ejected from Jeeps. Most of the time a high speed rollover will eject the passenger/driver if they are not in a 4 pt harness. The 4 pt harness is well worth the money, CROW makes nice restraint systems for a reasonable price. As for trail use, most of the time I just use the lapbelt.
