I'd agree not a US Army vest, well not anything they wear these days, I'd say its mthatsitsly if not all about plate carriers and those sort of chest rigs. That definitley looks like shady DPM of the british ex issue kind anyway, As CKinnerley said get on ebay or find your nearest surplus shop there more than likely to stock a generous amount of cs95 dpm as its now for the use of deployment and anything for the british obseletebritishearing certain things like cadets or maybe training excersises.MTP is the way forward in my opinion and its much better made the pockets are a lot better and the whole design.Ubacs are a good shout though or a good tactical hoodie for its cold at the minute.
As anything it's personal preference and if your happy with your gear then good for you dude ! Its nice to have advice of the guys on here.
