Yeah, soap is NOT expensive.
I am, however, looking for a good all-in-one. Something preferably liquid that I can keep in the shower for body, hair, face, etc. So far I've been doing OK with this giant costco bottle of shampoo a roommate left behind, but I have no idea what it cost.
My motivation is simply to keep things simple. I find it very hard to believe that your body will adjust to no soap by somehow killing smelly bacteria on the skin surface. More likely your nose adjusts and you stop being able to smell your own stench.
S - Sunblock is something I really want to avoid. I have dreams for extended outdoor activities, but am worried about the skin damage. Since style's not that important, I think I could do it with the right kind of SPF fabrics covering my whole body (like people in the dessert, but hopefully with more breathability, lighter weight, and more effective.)
