I'm glad our suggestions are helpful. I would just like to add, that at some point as you perfect the gear you carry, that you consider a compact synthetic fiber mummy bag of reasonable quality. You can do without it, but sealed away in double bagged plastic, it will make an impromptu evening out much, much more pleasant.

It will also come in handy in many outdoor situations - a real basic item. I am recommending against my preference which is down. Synthetic fibers are much better around water and humidity.
