I'm looking for a small low profile bag for an up coming backpacking trip.
It needs to be able to hold an un-gripped 5D MKII, a 17-40, a 50mm 1.8 and an 135mm 2.0.
I was looking at something like the shootsac, though I don't know if the Neoprene would hold up. I liked the shootsac because it was very thin and had just enough space for what I wanted to carry.
It will be warn while wearing a large back pack. And I would like it to have a removable strap if possible, as I could replace it to fit better with the backpack.
If anyone has any ideas for an alternative or DIY's of something they made for similar requirements your insist would be much appreciated!
