Pocketknife - A pocketknife is the most useful tool you can own. Keep yours clean and sharp.

First Aid Kit - Besides the complete first aid kit carried by your patrol or troop leader, bring along your own supplies to treat minor injuries.

Extra clothing - With layers of clothing, you can adjust what you wear to match the weather.

Rain Gear - A rain parka or poncho will shield you from showers and storms. In warm weather you can turn a large plastic trash bag into a poncho by cutting holes in it for your head and arms.

Flashlight - Finding your way in the dark can be tough without a flashlight. A sturdy one that uses a couple of AA-cell batteries doesn't weigh much, and it gives out a strong beam. Reverse the batteries during the day or put duct tape over the switch to prevent the light from coming on in your pack and draining the power.

Trail Food - The most importnat meal ofr hiking is the breakfast you eat before you hit the trail. Whether in camp or at home, a hearty breakfast starts the day right.
Carry a lunch in your pack. Sandwishes, fruit, nuts, and raisins are tasty. Or try crackers with peanut butter or cheese.
A small bag of granola, dried fruit, or a couple of energy bars can give you a nutritional boost between meals, especially if you are longer then you had expected.

Water Bottle - Fill your water bottle before you start out, and sip from it whenever you are thristy. In hot weather, you might need to carry several containers of water. Purify any water taken from streams, lakes, or springs before you drink it.

Matches and Fire Startters - With wooden strike-anywhere matches or a butane lighter (won't work on cold temperatures below 32F), you can kindle a fire in any weather.

Sun Protection - Too much exposure to the sun's rays can be harmful, especially if you have a fair complexion. Guard your skin with a sunscreen that has a sun protection factor (SPF) of 15 or higher. A broad-brimmed hat, lip balm, and sunglasses will give added protection.

Map and Compass - Carry a compass and a map whenever you travel in areas unfamiliar to you. Of course, they won't do much good unless you know how to use them, so take the time to learn.
