5 shirts, 3 pairs of pants/shorts, a homemade sleep sack, a swim suit, socks and undies . . . that's about it. I am still working on the extras, like my medicine cabinet, assorted toiletries, and sundries, but I think my bag will be decently stuffed.
You can survive on surprisingly little it seems, when you are forced to put it into a 25 lb sack.
Oh - and just to be absolutely nerdy, I took a walk today with my packed bag to see how heavy it was and to get weird looks from the neighbors.
