This list is only a general list and should carefully evaluated and added to as necessary. You may need different equipment for specific activities, ecosystems or to properly deal with your own body metabolism. Some items listed as optional may be required. You will need to be prepared for whatever possible weather conditions that may occur based on your location and the season. You should be familiar with the Environmental Hazards in the area and what personal equipment you will need to adequately safeguard yourself. If you are not familiar with the Dynamics of Accidents, please read that document as well. If you are not familiar with Hypothermia or Hyperthermia, please see those documents.

This list is designed for basic multi-day backpacking trips in temperate forest conditions in the United States. Typical temperature ranges would be 70's - 90+ Fahrenheit during the day with evening temperatures from 40's - 70's Fahrenheit.
The clothing layers should consist of several different types of fabrics. Cotton is comfortable and breathable in hot weather, but it absorbs and retains water, and therefore it will not keep you warm in cooler temperatures if it gets wet. Also it can be difficult to dry. For this reason you should not bring heavy cotton clothes such as sweatshirts, sweatpants or blue jeans. Cotton T-shirts and underwear are fine as are lightweight cotton shirts and pants. Polypropylene or other hydrophobic synthetic fabrics move the moisture (sweat) away from your body to the outside of the layer, reducing evaporative cooling. Wool or synthetic pile/fleece fabrics don't absorb water so they keep you warm even if they get wet. Pile also dries very quickly. A wool sweater or pile jacket provides warmth on a chilly evening. Nylon or Nylon/Cotton Windshells reduce convective heat loss. For raingear, coated nylon is lightweight and works well. Waterproof-breathable fabrics are also possible but are expensive.
The Layering System
Combinations of these types of fabrics creates a layering system. The purpose of a layering system is to be able to mix and match the layers of insulation to match the weather conditions and your activity level to maintain a comfortable body temperature without excess sweating (which can lead to heat loss). ). Throughout the day you will need to layer up and layer down as conditions and activity levels change. Typically in the morning and evening when it is colder, you will need many layers on. The inner layer keeps the skin dry and comfortable. Cotton provides good ventilation for the skin to keep dry and cool and during the day you will most likely hike in a cotton T-shirt and shorts. The middle layer provides some insulation and protection from the elements. Long-sleeve shirts and long pants make up this layer. You may wear these during the day for sun protection or in the evening when your activity level is low and it starts to cool off. The outer layer provides insulation and is usually a wool sweater or pile jacket. You will wear this around camp at night. The shell layer protects you from wind and rain. A waterproof rain jacket is essential in case of bad weather. The head layer is handled by a wide-brimmed hat for sun and rain protection. The feet layer is actually two layers. You should wear a lightweight synthetic liner sock against your foot which helps pass moisture away from your foot. On top of this you wear a wool/nylon blend hiking sock. People wonder why you should wear a wool sock with summer heat. Since wool doesn't absorb water it passes the moisture from your foot outwards, keeping your foot dryer. If your feet stay damp, they get wrinkled and are more prone to blisters. Having two sock layers means that your socks will slide against each other so that the friction from your boots is between the sock layers rather than against your skin (friction against the skin leads to blisters).
_______ Wool/Pile Hat (Optional)
_______ Brimmed hat (for sun protection)
_______ T-shirts - as needed
_______ Cotton Work Shirt - long sleeve
_______ Lightweight Synthetic Long Undershirt - polypropylene, or other hydrophobic, wicking fabric
_______ Lightweight Pile Jacket /Wool Sweater - (ex. Polartec 100™)
_______ Wind Jacket - nylon (can be same as rain jacket if waterproof/breathable - must fit over insulating layers)
_______ Underwear as needed.
_______ 1-2 pairs of loose fitting shorts
_______ Lightweight Synthetic/Wool long underwear bottoms - polypropylene, or other hydrophobic, wicking fabric (Optional)
_______ 1 pair long pants, loose fitting, light-colored cotton (No jeans - take too long to dry.)
_______ Swim suit (Optional)
_______ 1 pair of lightweight hiking boots: Boots should extend above the ankle and be leather/fabric or all leather with lug soles for traction. It is best if the boots can be waterproof, either by treating the leather with a waterproofing compound before the trip or if the boots have a Gore-tex™ liner. Boots should fit comfortably with two pairs of socks, a light liner sock and a heavy wool sock. Above all, make sure that your boots are well broken in before you arrive. Otherwise your feet will pay the price. We cannot emphasize this enough. Non-broken-in boots invariably cause chafing and blisters.
_______ 1 pair of running shoes, sneakers, or sandals: For around campsite wear and/or water activities.
_______ 2-3 pairs of light synthetic/polypropylene liner socks: Wearing liner socks underneath wool socks helps to prevent chafing since the friction is between the two pairs of socks, not between the boots and your feet.
_______ 2-3 pairs of medium weight wool hiking socks: Wool keeps your feet warm even when wet and gives good cushioning. The higher the wool content of the socks the better (we recommend 85% wool, 15% nylon).
_______ Gaiters (Optional)
_______ Waterproof Rain Jacket - coated nylon or waterproof/breathable fabric
_______ Waterproof Rain Pants or Rain Chaps - coated nylon or waterproof/breathable fabric (Optional)
_______ 2 1-quart water bottles or canteens
_______ 1 unbreakable cup with handle
_______ 1 unbreakable bowl
_______ 1 spoon
_______ 2 bandannas: multipurpose
_______ 1 flashlight with fresh, alkaline batteries (alkaline batteries last longer)
_______ 1 small towel
_______ 1 toilet kit: Just the essentials, biodegradable soap, toothbrush and toothpaste, comb, sunscreen, lip balm, insect repellent (no aerosols please). Repellents with high concentrations of DEET may be hazardous (do not use products with more than 35% DEET) or use a non-DEET repellent.
_______ 1 pocket knife
_______ 3 heavy plastic garbage bags - one for sleeping bag, one for inside backpack, one as a rain cover
_______ 1 pair of sunglasses or clip-ons
_______ 2 pairs glasses or contact lenses (if needed): If you wear contact lenses and will have difficulty cleaning them in the field it is suggested that you bring glasses instead. Please bring an eyeglass safety strap for your glasses.
_______ Any medications you will need to take during the trip (allergy medications etc.).
