MSR Trailshot Water Filter

Tiny enough to fit in your pocket, important enough to save your life. So goes the spiel for the MSR Trailshot Water Filter. This highly portable implement filters out 99.9% of protozoa and bacteria, and can handle up to one liter every minute. It also lets you drink directly from streams and lakes — no bottle required — and lasts up to 2,000 liters, or more than enough to keep you alive for a couple of years, at least.
