For backpacking & disaster preparedness - Polar Pure Water Disinfectant

Iodine based purification that does not expire. It's lightweight, saves space, and purifies the water as any iodine-based purifier. I like the fact that it doesn't expire. I use iodine as a backup to my filter or as a light alternative on day-hikes. Be careful with the glass bottle. The company says[...] Don't let it freeze. Don't drop on the rocks.
