Feel the need for more trail selfies? Instead of a heavy tripod, support your iPhone for 38g (1.3 ounces) or your small camera for 30g (1 ounce). This kit goes on top of regular bottles like the 1 liter sparkling water bottle that is always in my pack.
There are two basic parts: a water bottle camera mount and a tripod adaptor for an iPhone (or other phone). If you have a lightweight camera, you can skip the phone mount and save 8 grams.
I’m seeing more and more backcountry books that suggest using hand sanitizer by itself. That does not work. Soap and water is necessary, sanitizer is optional.
The Scouts Backpacking Cookbook is one of those with that bad advice. The BSA Handbook gets it right. Wash your hands with soap and water.
Clean hands are important in the backcountry. People who know, like Tod Schimelpfenig, Curriculum Director at the Wilderness Medicine Institute of the National Outdoor Leadership School, believe that dirty hands are a bigger health risk than dirty water.
