Its hood and torso have synthetic insulation that traps in heat to keep your core warm, while its sleeves and sides feature stretchy, breathable fabric that encourages airflow and helps you move freely. The adjustable hood and drop-tail hem keep gusts of wind from sneaking in to chill you, and the zippered pockets secure small items or warm your chilled hands when not in use.
