CiloGear,Osprey, ArcTeryx, CCW, Dana Designs, Gregory, REI, Jansport, they all have the exact same suspension system or close enough to the same.
It stinks. Actually, they suck, as all of them are not stiff enough. I have used, Dana Designs, Osprey, Gregory, CCW, NF, Arc Teryx, and had my hands on CiloGear and REI etc. They are all the same. The only difference is their outside pockets. Big freaking deal. They still Stink.
All of these packs are horrid at hauling loads. IE 75L size and above for things like Winter, bumming around.
If you have the money, get a McHale backpack. Its suspension system gets the stress off of your shoulders and transfers it to your hips. I can't really describe the difference, but it is extreme and far more comfortable. His packs are also made to last forever using spectra etc.

The website isn't all that great, but search and you shall find. The Critical Mass Packs are awesome. I own 2 of them bought 2nd hand so got an amazing deal.
I have a Dana Designs 75L pack and Gregory Denali Pro for sale if you wish. You can have either for $150. The Dana is burnt orange and in excellent shape that I picked up for someone else, but they never used. The gregory is highly used but resealed.
