Basic Gear
• Packs
• Stoves
• Lighting
• Little bits:
• Knife, spoon, duct tape
• Map, Compass and Whistle
• Emergency Bits
Packs: Types
• Daypacks– Short trips, minimal waistbelt
• External-frame– Not for winter --- too unwieldy
• Internal-frame– Winter favorite
• Daypacks, I-frames for rent
Packs: Theory
• Hipbelt takes most of weight
• Shoulders mostly stabilize
• Constantly adjust straps to keep fit as load changes
Packs: Packing
• Bottom --- light (sleeping bag)
• High, close to back --- heaviest (water, food, fuel)
• High, far --- midweight (stove, clothing)
• Frequently used items in pockets to avoid opening main pack
Stoves: Use
• Melting snow --- put water in pot to avoid scorching
• Boiling water
• Fancier foods
Stoves: Types
• Butane, Butane/Propane, Isobutane– Pressurized gas canisters– Very easy to use– Poor performance in cold weather
• White gas– Liquid fuel turned to gas just before burner– More difficult to use– Winter favorite
Lighting: Flashlights
• C, D-cell flashlights too big!
• AA flashlights useful, but need a hand free…
• Headlamps! LED or Halogen
• Lithium batteries better in cold
(More on batteries later in WS)
Lighting: Headlamps
• Halogen: bright (2 hours on 2 AA)
• Xenon: long-lasting (8 hours on 2 AA)
• LED (new): absurdly long-lasting (100 hours on 2 AA)
• Separate battery packs can be kept inside clothing

• Map– Each person carries one in a waterproof bag
• Compass– $10 compass is plenty
• Whistle– Plastic (sold during office hours)
Handy necessities
• Swiss army knife / leatherman
