Hello, I will begin section hiking the Appalachian Trail this year. Right now I can only take off two weeks at a time (per year). I am new to overnight backpacking, but am an experienced day hiker. I'm sure I will have many questions as I continue to prepare.

Here's my first question: I am planning on my first two week section hike in late May or early June of this year. I will be starting at Springer. Now the question. Will I need to pack a puffy jacket? I have an REI Quarter zip fleece pullover. Will that be enough?

Thanks for your advice.
