The "Backpack" holds weights or the battery for my monitor.
So a while back I made a handle/rig for my gripped t2i, but after using it for a while I found that it was a bit too cumbersome, heavy and a pain to take apart. So I started looking into other handle systems like the x-grp and cam caddie cause I see a lot of other skate filmers using them, but in the end I just couldn't bring myself to spend money on something that I can make myself. So I took the grip off my t2i and designed a new handle that feels and works perfect for filming skateboarding. I've used an Eazy Handle before and although this does not feel quite as good it sure is close enough for me.
