I like the new version.

In 2003 The Mountaineers revised the essential list as part of the 7th edition of "Mountaineering: The Freedom of the Hills" to keep up with modern equipment. The current edition, 8th edition continues with the new essentials list with no major revisions. The new list takes a "systems" approach.

Navigation (map and compass)
Sun protection (sunglasses and sunscreen)
Insulation (extra clothing)
Illumination (headlamp/flashlight)
First-aid supplies
Fire (waterproof matches/lighter/candles)
Repair kit and tools
Nutrition (extra food)
Hydration (extra water)
Emergency shelter (tarp, bivy bag, space blanket)
