Bringing the 10 Essentials on every adventure is something all hikers, backpackers, and adventurers should make second nature. Most day hikes and backpacking trips won't require the use of every item, but having the 10 Essential in your pack when things go south, could be a lifesaver.
The original 10 Essentials were developed by the Seattle-based Mountaineers Club in the 1930s and first appeared in print in Mountaineering the Freedom of the Hills, 3rd edition, published in 1974.
In 2003, the Mountaineers published the 7th edition of Mountaineering: Freedom of the Hills, 8th Edition with an updated 10 Essentials to account for new technology and equipment. The Freedom of the Hills is a great resource for both mountaineers and hikers, covering many survival and mountaineering techniques that every outdoor enthusiast will find helpful while exploring the backcountry.
The updated 10 Essentials takes a new approach that the Mountaineers call the System Approach. Whereas the previous 10 Essentials List had consisted of 10 individual items, the Updated 10 Essentials List consists of 10 Systems that can be composed of multiple items. Don't worry if this sounds overwhelming we are going to cover each system below.
Bring a topographic map on every hike, especially when hiking in unfamiliar areas or when taking a complicated route. Combined with a compass, a map can be the difference between being lost overnight in the backcountry and an epic adventure story to recount at the bar after the hike. You can also consider letting technology do your navigating with a GPS and Altimeter. However; these should not replace your map, compass, and navigation skills since they have limited battery life.

No one plans on getting a sunburn, but the hike you thought would only take an hour can sometimes take three, so always pack your sunglasses, sunscreen, hat, and light weight clothing for sun protection to protect your skin from getting an overdose of sun.
Have you ever noticed that the weatherman is usually wrong? Don't count on that perfect forecast when heading into the backcountry, the weather can change rapidly and unexpectedly and if you aren't prepared with extra clothing you can end up wet and cold or worse. The Mountaineers recommend bringing enough clothing so you can survive the worst realistic conditions that you may encounter. Items to consider are rain gear, long underwear, hat, gloves, synthetic insulated jacket, extra hiking socks etc.
We prefer headlamps because they are lightweight and keep our hands free, but a normal flashlight will get the job done. Just as important, are extra batteries, because you don't want to be that guy who's light goes out 3 days into a 4-day backpacking trip.
Pro Tip: We keep a small backup keychain led light in our first aid kit.
You can create your own first-aid kit or go with a premade kit that will fit your needs. We like to go with a premade kit that we can then supplement with additional items to fit our needs. Make sure your first-aid kit includes a selection of bandages, anti-bacterial ointment, gauze pads, medical tape, pain medication, and gloves.
Many of the backcountry destinations we enjoy don't permit fires, but in an emergency, you may need to build a fire to survive. Pack a lighter, waterproof matches, and a firestarter and you should be able to get a fire started when you need it.
A good knife or multitool has so many uses that it should be in your pack every time you hit the trail. A few items we like to add for random gear repairs are paracord, duct tape, and safety pins.
Pro-Tip: Wrap duct tape or paracord around your water bottle and it will be there if you need it.
Bringing enough nutrition for an extra day in the backcountry doesn't mean you need to have an emergency breakfast, lunch, and dinner in your pack. Keep things simple by bringing a few extra granola bars, beef jerky or other items that are easy to carry.
Hydration is particularly important when hiking in the backcountry. Carry more water than you think you will need and drink often and early. The Mountaineers recommend bringing a water bottle and a collapsible water reservoir. You should also carry a filter or chemical purification system and plan on replenishing your water when you can.

10. Emergency Shelter: Tent, Tarp, Bivy Sack, Poncho, Space Blanket etc.
Emergency Shelter is new to the 10 Essentials List. Shelter is something many day hikers might not consider bringing, but something as simple and light as an extra large garbage bag or tarp can help keep you warm and dry if you end up spending the night in the mountains
