I use the ThinkTank system but the LowePro is very good too. I can only really comment on The ThinkTank System. They have 3 levels of belts, thin skin belt no padding, pro speed belt (padded) and the heavy duty padded steroid Belt with some back support.


You can buy different components to hang off of it. Some people like no padding and then they store the lenses in the skin pouches for easy packing into another camera bag (because the skin pouches take up less room) and some people like the slighltly padded modular components for the extra protection when the lens is hanging off of the belt in case you bump into anything.


I happen to have the pro speed belt and the full modular system with the pixel racing harness shoulder strap.


What ever belt system you end up with, make sure that the opening for the lens pouch opens away from your body to make it easier to put the lens back in it. The lens changers have quick access draw string so you don't have to deal with zippers. If I were to going hiking I would probably like the security of the zipper better, plus the zipper will keep dirt out better on a dusty trail, however for fast lens changes I like the draw string better. They also come with a rain cover that stows inside.


If you have any other questions about the Think Tank System or what fits what, then just let me know.
