Machine wash. Imported Size S, 4-6 Layer on the weightless warmth. Super light, yet oh-so warm, you'll make up excuses to throw this vest on. All thanks to its 800 fill power down. It is one of the lightest (and warmest) chill-blockers out there. It even retains its loft and warming power when gets wet. What's better? It’s made of special, antistatic thread to protect against excessive feather leakage. No molting here. This vest is a flattering top layer when paired with jeans and a tee during cooler months. However, it also serves as a valuable middle layer when temps dip. Plus, this vest is packable. Throw it in your vehicle or canvas tote for grab-and-go warmth whenever sudden chills lurk.
