They are big, that's why I picked them. When I head for the office, I can stick my laptop(11"x14") in one side and my rucksack in the other(folded over). Then when I get to the office, I can pull out the ruck, put the laptop in it, and head inside. Here in the Texas Gulf Coast, it is already pretty hot/sticky, and not having the ruck on my back when I ride keeps it cooler.
One side of the bags has some dividers and inner pockets, the other is one big space.
And for Chief Gunner, I put one of the rain covers on this morning for the ride to work. They are form fitted, with good elastic and a draw string. They fit over from the outside, and the elastic holds the edge next to the bike all the way around. I did not use the drawstring, but coulld not hear/feel/see any thing flapping.
