When it fails—which happens with poorly designed or poorly fitted packs—you experience sharp shoulder pain, numb fingers, lower back strain, and a powerful urge to put the pack down. The difference between success and failure comes down to specific design choices in how a pack is built.
Most people think about backpacks as containers. You have stuff, you put it in a bag, you carry it. This is partly true, but it misses the engineering. A backpack is actually a system for managing three problems simultaneously: how to distribute weight efficiently across your body, how to keep that weight stable and balanced as you move, and how to keep the pack itself from failing under stress. Solve those three problems well, and you have a useful tool. Ignore them, and you have an expensive piece of fabric that hurts to wear.
