Membrane Solutions Straw Water Filter
The creek down the hill is drinking water now.

How John uses it
There’s a creek about 400 yards from the cabin. I don’t drink from it casually — the cabin runs on a filtered rainwater system — but if that system is down for a week, the creek goes from scenery to utility in about a minute with one of these in the pack.
I also keep one in the truck. Tennessee has water almost everywhere. Being stranded 30 miles out with an overheated engine is a survivable problem if you can drink what’s running beside the road.
Why John recommends it
Dehydration will end a bad day faster than almost anything else. A straw filter is the lowest-friction water tool that exists — no pump, no waiting, no chemicals. Drop it in the pack and forget it until the moment it’s the most important thing you own.
