Brightly colored traffic cones come in handy on the road. You can use them roadside in a towing emergency, to mark a parking space at a trailhead, or to indicate a tricky spot on the trail. Each Safe Warning collapsible cone telescopes into its base to form a nine-inch square just two inches thick—easy to store in your rig or even slip into a saddlebag. When fully extended, the bright-red cone measures 16 inches tall. A three-inch band of reflective tape around the top enhances the cone’s visibility. The base is wide enough to hold rocks, for stability.

Cost: $20 each.
