Did a little research because I didn't have anything else to do today. The original xBone was designed to work with the Eco, Klassen and I think Action Products vest. The xReach also works with the Exo vest and others. The xBone CF makes no mention of working with Exo (from the flowcine site) and couldn't find any information on an adaptor. Doesn't mean one doesn't exist or that flowcine couldn't make one.
