Crow Sternum StrapsShown in the photo, are the 2 Crow sternum strap latch options.
The function of a sternum strap, is to keep the shoulder harness from spreading apart and slipping off the shoulders even during an impact. As you can see, you can choose either the Velcro or the latch & link style latch. It can be added to any of crow racing seat belt or off-road harness.
The sternum strap is sewn into your shoulder harness straps (restraint), but in most cases, it will not delay shipping of your Crow seat belt. Also, adding a sternum strap makes the harness a custom item, so it is not returnable.
