Review: Grayl GeoPress Ti Purifier

On more than one occasion, I’ve had the misfortune of running out of water or having my bladder hose freeze while I’m backcountry hunting or skiing. Hence, my interest in the GeoPress Ti Purifier from Grayl. Simply fill the outer container, made from titanium, and then push the inner press with the water filter down—and voila, you instantly have 24oz. of fresh water. Plus, the outer cup can be used on a small stove or even open flames to heat water for dehydrated meals or a warm drink. Available at grayl.com; $220.
