Why We Love This Deal

For some, the arrival of winter weather means it’s time to bring the workout routine indoors. For others, the only thing that changes is their outfit. If you’re still running, hiking, and biking this winter and want a little extra coverage, REI has an awesome deal for you: Right now, an ultralight Arc’teryx jacket is a rare 20% off, and plenty of sizes are still in stock.
