The Sportful Hot Pack 6 Vest is the windproof layer you need to keep your core warm as you ride. Its weather-resistant design deflects wind and light precipitation to prevent your core from losing heat as you pedal. Sportful designed the Hot Pack 6 with a stretchy construction to ensure you can move however you need to on the bike, and gave it an extended collar and a drop-tail hem to ensure coverage on or off the bike. Rear vents provide plenty of airflow without exposing you to the elements, and an integrated stuff sack compresses the vest down to practically nothing so you can take it on every ride.
