The Ten Essentials first appeared in print in the third edition of Mountaineering: The Freedom of the Hills (January 1974). Many regional organizations and authors recommend that hikers, backpackers, and climbers rigorously ensure they have the ten essentials with them. However, personal preferences and differences in conditions may dictate otherwise and with experience most adventurers add and subtract from the list depending on the situation. Some ultralight backpackers do not always carry all of the items and believe it is an acceptable risk they take in order to travel light and fast.
- Navigation: map, altimeter, compass, GPS device, personal locator beacon
- Headlamp: with LED bulb and spare batteries
- Sun protection: sunglasses, sun protective clothing, sunscreen
- First aid: a first aid kit
- Knife: knife, repair kit, multi-tool, tape, rope
- Fire: either a butane lighter or matches, fire starter
- Shelter: plastic tube tent or jumbo plastic trash bag
- Extra food
- Extra water
- Extra clothing needed to survive the night in the emergency shelter
Other outdoor organizations have variations of the Ten Essentials pertinent to local conditions.
Boy Scouts of America's "Scout Basic Essentials" are quite similar (Map and Compass, Sun Protection, Extra Clothing, Flashlight, First-Aid Kit, Matches and Fire-starters, Pocketknife, Trail Food, Water Bottle, and Rain Gear.)
The Spokane Mountaineers list "thirteen essentials", which supplement the list with emergency shelter such as a space blanket, signaling device, and toilet paper and trowel (for sanitary disposal of human waste; the toilet paper also doubles as tinder for starting a fire).
The "Ten Essential Groups" is an alternative approach to essential gear selection. Items from each group should be chosen depending on the season, geographic location, and trip duration. In 2011, Columbia Sportswear adopted the "Ten Essential Groups" concept for their iOS app "Take Ten to the Greater Outdoors".
Central Arizona Mountain Rescue Association promotes the 12 Essentials, which includes Signaling Devices and Personal Items.
