All Terrain HandSanz There are dozens of hand-sanitizer gels on the market, and we’ve tried them all. Like most of its competitors, HandSanz employs ethyl alcohol as its active ingredient. But unlike the rest–which typically use a synthetic polymer thickener called Carbomer–HandSanz relies on wood cellulose and vegetable glycerin, which act as a natural thickener that also moisturizes. The silky fluid kills germs, bacteria, and other nasties. The airport-security friendly two-ounce bottle is recyclable and can be refilled, cutting back on packaging waste. While we like the extra-moisturizing effect of the Aloe & Vitamin E formula, the fragrance-free version is our choice for bear country. $3 (2 oz.); $6 (8 oz.). (800) 246-7328; allterrainco.com.
