So what's the deal with the PVC? does that act as a pre-filter or is it just a carrying case? Is the life straw that fragile? Have you tried the Sawyer products?The get-home bag, packed with food, etc. A tarp or two. Parachute cord. Knives, hatchet. Assorted medicines. A couple of armored Life-straws. Lighters and cooking/eating utensils. Road flares (easy to make fires with them, even in the rain.) Soap & toiletries. A bunch of coin tissues. Flashlight & batteries. A hand-crank radio.
