Mostly less than 5 pounds (lock on occasion, extendable baton). No more patch kit or pump since I went to Schwalbe Marathon Supremes. Some days a little more weight if I need to bring in fresh clothes (usually do that when I drive).

Funny though that after a few weeks of commuting and recreational riding the bags seem to accumulate stuff and I need to clean them out. "oh, there's my IPAD!"
