I'm going on a guided trip and I have learned a lot from reading this site and others. I clearly need to eliminate some things now that I am really packing for my trip (next week)..but I'm shipping my pack ahead of time. They'll go over it all with us before we head out but...silly questions/thoughts...

What do I sleep in? I am sharing a tent with a stranger mind you. Hairbrush? Not a necessity but I am woman with long hair and I suspect 4-5 days w/o brushing will mean a big fat dreadlock mess. Deoderant? They didn't put any deod/soap on our suggested list aside from toothpaste and wipes and now I read it should be unscented. So go with my small scented or ? Any advice at all is welcome!
