Lowepro Pro Runner BP 450 AW II
Before the Pro Trekker was introduced, the Pro Runner or the Protactic are the two options when you have a lot of gear. I prefer the Pro Runner if I am going to be hiking some distance due to the bags very well padded shoulder straps.
Lowepro Pro Runner BP 450 AW II versus the Lowepro Pro Runner BP 350 AW II, which one do you choose. Pick the Lowepro Pro Runner BP 450 AW II if you have DSLR's with battery grips.
