I've done it a bit, though not recently.

Honestly the best thing to do is to do is gather the obvious things (portable stool, easel, brushes, paints, canvas etc) and then go out and do it. Then you will very quickly realize what you need or don't need. Like maybe you will go "oh fuck, I didn't bring any rags or paper towels with me" and you know to bring it next time. Or "crap, the wind keep blowing over my easel, I need a weight on it". "Fuck I'm thirsty in the summer heat, I should bring a water bottle". "Dammit, I don't have a way of transporting the wet finished painting easily without smearing oils over everything".

There's a lot of people who have written excellent blog posts listing all their preferences, but at the end of the day that's what works for them and may not work for you. Get outside, paint, fail, get frustrated, and figure out what things you find you will need to bring next time (or leave at home next time).

Also you don't need any fancy expensive pochade boxes or anything. You can build most yourself or just make do with cheap things and find solutions around things. For example you can stick the wooden end of your wet brushes into the ground so they stand up vertical and you don't need to hold them in your hand or use a fancy pochade box with holes in it for them.

It depends on what you use; oils, watercolor, guache, acrylic etc

I paint with oils and I use a french easel and backpack to carry everything i need, though usually not too far from my car. My French easel is the easel and holds my palette and spare paints as well as lidded palette cups with my turp and my medium. My backpack has paper towels, trash bags, brushes, silicoil jar of turp, and spare medium. My medium is usually straight liquin

Nathan Fowkes and James Gurney both use watercolor and guache outside and their sets don't include any easel, but you can find it online at one of their blogs.
