What to Pack For a Trip to Yellowstone, According to a "Yellowstone" Fan

Ski-Doo Women's Insulated Exodus X-Team Edition Jacket ($359)

I wore this insulated jacket while riding my Ski-Doo around Yellowstone, and not once did I get cold. Not only does this jacket have a zipper to keep all my clothes tucked in, but it also has buttons on top of the zipper that really lock in the whole outfit.

Plus, there's no shortage of pockets: there are two hand pockets, one chest pocket, and one pocket inside the jacket. This is important because, when you're seeing as much wildlife and beautiful scenery as you are in Yellowstone, you want to be able to quickly pull your phone out of your pocket to capture it.
