Dennis – I’ve been issued probably half a dozen SOC bags in various sizes over the past 10 years- everything from a small ~25-30 liter bag up to around 60-70 liter bag. I would not recommend them for bugout purposes. I’ve had at least 3 bags rip, either along/near zipper seams or where shoulder straps meet the bag. I’ve also had multiple zippers break/snap (because they are absurdly poor quality zippers). Additionally, the bags that do come with belts use very cheap belts that will offer zero support. I will also caveat all of this to say that I’m not a ground pounder who is abusing this stuff in the field. It carries my equipment to and from the aircraft and on a daily basis to the office. The bags offer a lot of storage/organizational options and would likely be well suited for a light afternoon hike/picnic or even as a ‘get-home-bag’, but I wouldn’t want to rely on them in more of a ‘bug-out’ or survival situation.
