Right now, you can pick up a Patagonia Houdini windbreaker for just $31.83 at REI. That's an enormous saving of 70%, and applies to the jazzy Thriving Planet/Core colorway. You'll need to move fast to grab it, though – REI traditionally closes its physical and online stores on Black Friday, so you won't be able to buy it tomorrow.
I own a Houdini myself, and I definitely paid a lot more than that! It's an incredibly useful little jacket that can be stuffed inside its own pocket and stashed in the side pocket of your backpack for whenever the temperature starts to drop. It's water resistant rather than fully waterproof, but it does an amazing job at blocking out icy winds, and I use it as my default running jacket throughout the winter.
