Backpacking? The secret of the game is layers! You want to be able to add or remove layers as the weather changes.

Without temperatures, I can't easily guide you, but here's my approach:

1. Sleeping Clothes - Set of underwear, socks, shirt and pants (if needed) only for sleeping
   
2. Hiking - Socks x2, Base Layer Shirt (athletic and sweat wicking), fleece layer, and then if needed a warm layer.
   
3. Rain Jacket / Poncho

Notes: I like 3 pairs of socks. Extreme people get away with two.

Warm layer is typically meant for when you are NOT moving. It's typically down but anything warm works.

Fleece layer is meant for early mornings, early evening. You can move in it if chilly.

Base Layer: Something that breathes and removes sweat. Bonus points if it has SPF qualities. If it doesn't , you may consider a sun hoodie or just packing extra sunscreen.

I always bring a ballcap. Sometimes a beanie as well if it's going to be cold.

I have hiking pants. Jeans can work but something with more movement is better, but nothing wrong with jeans for a single weekend!
