Not a big issue right now but it could be in the future, some "cloth" armor has the same or more hull than "composite" armor. An Armor's hull determines how long the armor will last before falling off your chest or being useless (likely from close range explosives). In particular the BARC armor has one of the lowest hulls while the flack jacket is rather high on the list compared to others, not saying it isn't tough and durable just a strange comparison with other more durable armors.
