Super light, yet oh-so warm. You'll make up excuses to throw this jacket on thanks to our 800 fill power down. After all, it is one of the lightest, yet warmest, chill-blockers out there. Not to mention it's water-resistant, so no need to fret if it gets wet. What's better? We use a special, antistatic thread to protect against excessive feather leakage. No molting here. This jacket will be your MVL (Most Valuable Layer) when temps dip. Plus, it's packable! Just throw it in your bag or backseat to easily grab and go.
