I just got done doing a 4 day trip around Lake Michigan and I picked up a set of Fieldsheer expander saddlebags.
Fieldsheer Expander Saddlebags - BikeBandit.com
I was very happy them. I managed to take quite a bit of stuff with me for this trip. (More than I needed, I realize now).
When I packed for the trip, I expanded the bags and by the time we were on our way home, I was able to compress them down, due to eating or throwing away some of the things in the bags and putting dirty/wet clothes in a stuff stack lashed down on top of my tent and sleeping pad.
In one bag I put all of my clothes
-Extra pair of jeans
-Pair of shorts
-Pair of swimming trunks
-4 pairs of boxers
-4 pairs of socks
-3 t-shirts
-1 long sleeve thermal
-1 hat
-2 pairs of riding glasses
-rain suit
-small bath towel
Plus I also got a misc. things and extra ziplock bags in the outer pocket.
The other bag I packed:
-Tools
-Fruit bars
-Beef Jerky
-Sunflower seeds
-Sleeping bag
-Shower Stuff
-Personal Hygiene Stuff
-Rain Covers for the bags
-Cutting board
-A few small cooking items
-Camera, extra battery, extra memory card, 12 volt charger
-12 volt phone charger
On the back of my seat I strapped down my tent (3 man backpacking tent), a self inflating sleeping pad, my flip flops, a water jug and a stuff sack with my dirty and wet clothes.
Overall, I was VERY happy with the bags. They seemed to sit well on the bike, not too much sag. However, I do plan to rethink my mounting plans for next time, as i think I could still set it up better.
I also think, next time I'll change up my packing style a bit as well. Maybe a few less clothes and stop some place to wash things. Also, get more "mini" size things like shower soap, etc and maybe get one of those small, quick try camp towels.
Here is a couple of pictures as well:
