A map and the tools you need to read it could get you home safe—no charging required.

GPS will lead you around the paved parts of the world, but tapping on a smartphone screen won’t always work in the wilderness. For backcountry adventures, you’ll need to be comfortable going analog. These tools won’t give you turn-by-turn directions out of the woods, but taking them along could save you from shacking up with a bear for the rest of your days.

1. Maps

Regional outfits like Outdoor Trail Maps in Colorado or the ­Appalachian Mountain Club in the Northeast provide local details, such as trail routes. They also have standard cartographic info like elevation, GPS coordinates, and the topographical lines that show terrain contours.

2. Sleeve

Thanks to a zip ­closure with heat-welded seams, the Sea to ­Summit TPU translucent envelope will protect your precious chart in ­water up to 33 feet deep. The 12-by-8.3-inch thermo­plastic urethane case is also freeze-​proof, so it won't crack. Eyelets provide a way to lash it down.

3. Pencil

Savvy wanderers annotate their guide—say, by adding an X to mark their destination for the day—to make it even more useful. A ­mechanical pencil such as the ­Zebra M-701 stays sharp, its ­stainless-​steel case won't corrode in moisture, and textured knurling helps you grip it.

4. Compass

Use the transparent ­Suunto A-30 compass to orient the map so it's lined up with magnetic north. Then, measurements on its side will help you interpret the scale so you can figure out that the 1 inch of paper between you and a lake is a really freakin' long walk in the real world.
