Outside Online looks to NOLS Wilderness Medicine for tips on how to build a well-stocked first aid kit. The first step? Making sure you know how to use all of the supplies you're planning to pack—consider taking a wilderness first aid course to prepare.
“First and foremost, the best first-aid kit you can have is one you know how to use. If you spend a decent amount of time in the backcountry, we highly recommend investing in a wilderness first-aid course. It’s only a weekend of your time and could save a life one day. Having every type of Band-Aid under the sun doesn’t matter if you don’t know when to use them or what wounds they’re best for. Dig deep in an informative first-aid guide—like the NOLS Wilderness Medicine book—and learn how to use first-aid tools correctly.”
