You have to stay outside without any shelter for at least 36 hours in gusting winds, pouring rain and possibly snow. You also are unable to use anything made with synthetic materials.

What do you wear?

....and where do we buy it?

I am trying to cut out any Petrochemical/synthetic item I can out of my life, including clothing. Needing to buy a new winter coat/jacket, I have been hard pressed to find anything that is made 100% percent natural and waterproof. I thought of waxed canvas, but even those are lined with polyester inside. Not for "climate change emission" reasons but for health and for the real environmental disaster, microscopic chemical pollution.

Also, general all-natural /out/ supply thread.
