<bot>: For a 3-day backpacking trip in mild weather, you should bring a lightweight jacket, long-sleeved shirt, shorts or pants, socks, hat, and a pair of comfortable shoes. Don't forget to pack extra layers if you'll be spending time in the evenings outdoors. Depending on the temperature, you may want to bring additional warm items, like a sweater or fleece. Bring a rain jacket as well, just in case. Lastly, don't forget to pack any accessories you might need, such as sunglasses, sunscreen, and a hat.
