All-in-one jacket, tent and sleeping bag - just $250!

I've got an oil skin coat. I's heavy, big, not that comfortable but I like it - it feels good. The whole light weight material thing just doesn't give me the same vibes.

So this one is for all you latte-sipping hippy hikers who pull the second row of sticking out of your undies to save weight. Enjoy.

Would it really be useful?
