What gear do you need to go on a backpacking trip?

To go on a backpacking trip, you'll need a few categories of items: shelter, cooking and clothing. Start with a trekking pole tent like the X-Mid Pro. Don't forget 2 trekking poles. You'll need a sleeping pad like a Klymit Static-V and a sleeping bag or quilt such as the Kelty Cosmic 0. In order to cook and boil water, you'll need a stove such as a Jetboil and the corresponding fuel to power it. As far as clothing goes, several layers of wool/synthetic fabric with a light shell will work great at keeping you warm and dry. All of this needs to go in a backpack that's of the right capacity and sized to your frame.
