What Our Gearhead(R) Experts Are Saying:"This is the layer I grab when I want something light, warm, and low-maintenance. THERMOBALL(TM) insulation keeps me warm even if it's damp out, and it packs into its own pocket for easy stashing. I've used it for hikes, chilly commutes, and layering under shells-it just works."Whether we're heading into the hills or commuting across town, the ThermoBall Jacket keeps us warm and ready without weighing us down. Built with 100% post-consumer recycled THERMOBALL(TM) insulation, it mimics the structure of down to trap heat efficiently-without losing performance in wet conditions. That means we can count on it during shoulder-season hikes, damp morning starts, and light drizzles. The WINDWALL(TM) recycled polyester shell and lining provide wind resistance and breathability, while a non-PFC DWR finish adds light weather protection. Thoughtful details like secure zip hand pockets, an internal draft flap behind the front zip, and an adjustable hem round out this daily workhorse. As part of The North Face's Circular Design initiative, it's made with recycled materials and built to be recycled again, giving the jacket a second life long after ours.
