That Camelbak I'm guessing is a CBMR which is manufactured by Mystery Ranch, I have a NICE 6500 manufactured by Mystery Ranch, the system is really good...they have three different frame types one is the standard NICE Frame which can bear 100lbs, the Overkill can bear 150lbs, and STRLLS Frame which is designed for airborne operations...the external system has a lot of advantages it being modular and you can take off your big 6500 ruck and put something smaller on. Mystery Ranch also makes a pack for SOCOM which I could and should have purchased at the time when I was at the factory getting the run down from Dana Gleason(the owner), it's available to the public. When I end up having to replace it...and I'm sure by that time the entire system will be updated, more modular and lighter. He builds the best stuff in the business, just a little pricey.
No problem =]
