So, that filter is called the Sawyer mini. It's a much finer membrane than what's on the lifestraws, so it filters out a lot more bad stuff. I've not used a lifestraws, but the flow rate through the Sawyer is really really slow. The end that goes in the water can screw onto a water bottle. I'm gonna experiment with picking up a trash bottle and using that. It'll get me water for the day and I'll be picking up trash. The trash cleanup out there is a big project by itself.

I've not tried the poison ivy soap specifically, but I did used to have a bar of soap that had plantain in it. It worked well. Plantain is a good remedy for poison ivy.
