The North Face ThermoBall™ Vest - Men's

The North Face ThermoBall™ Vest packs synthetic insulation that mimics the warmth and loft of down but keeps working when wet, making it the perfect core-warming layer for unpredictable mountain weather. This versatile vest compresses small enough to live in your pack year-round while delivering instant warmth when you need it, providing that goldilocks insulation for high-output activities where a full jacket would turn you into a sweaty mess.
