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. It even retains its loft (and warming power) when it is 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, this it is packable. Throw it in your vehicle or canvas tote for grab and go warmth wherever sudden chills lurk.
