In this tutorial, we learn how to fit a backpack for long distance hiking. For scouts, look for a backpack with an adjustable torso so the pack can grow with you. After this, have the sales staff help you adjust your pack correctly, and measure how long the pack is on your back. You want the pack to fit you perfectly so you don't have back problems later. Try the pack on both on the hip section and shoulder to see how it feels on you. Tighten any adjustments to make it more secure, then you will have an evenly distributed weight on your backpack!
