Spring triggers intoxicating evidence of all that Mother Nature provides, from wildflowers to bursts of green foliage to sunlight that stretch far into the night. And it also unleashes the ursine population, who have woken from their seasonal hibernation ready to re-enter the forest and start eating. Bear bags and canisters are essential for backcountry camping, but even day hikers can easily encounter a hungry bear. To level the playing field—or at least announce your presence to the skittish bears—outfit yourself with the aluminum Coghlan Bear Bear ($4). Clip the bell to your pack, clothes, or trekking pole via the hook-and-loop strap, and you’ll let elicit a steady warning sound to warn all animals of your presence. Better still, when you’re away from danger zones, you can drop the bell into the attached bag, and a magnet will silence that now-annoying ringing.
