GPS, tent, sleeping bags, cloths, food and water. Everything that two guys need to survive for 4 days. We had dry bags that did wonderfully and also one large duffle bag that we kept other stuff in. The only things in the dry bags were electronics and cloths and sleeping bags. Everything else was in ziplocs or just got wet.

I have a full write up that is almost ready, I will add it to this post sometime soon.
