It's a 511 push pack and I still have room in the main compartment for something the size of two regular bricks. And PLEASE don't take what I have said or what I have in my kit as gospel, I am also a noob at this but have gotten VERY valuable information and help from Arch and others that are far more knowledgeable about this than I am.
