Camping is great, except for the whole not-having-a-place-to-bathe-other-than-a-frigid-stream thing. That part, well, it kind of sucks. I, for one, need a warm shower to get going in the morning, and the lack thereof makes camping less fun for me.
Problem solved! Just bring along one of these solar showers in a bag. It holds 20 liters of water, and if you leave it in the sun for a few hours it'll get nice and warm. Hang it from a branch, get nice and naked, and enjoy a warm shower in the middle of the woods. Now that there are no excuses, you might as well get out there and start roughing it. Just don't forget your Blackberry.
