The North Face Ventrix Jacket
Tackle the challenges of rapid elevation gain and loss with this new, lightly insulated jacket that features state-of-the-art Ventrix™ ventilation for balanced warmth and breathability. Perforations in key areas are designed to expand and dump heat or contract and retain as you move, so you won’t overheat or sweat out.
New, dynamic ventilation responds to your body movements during aerobic activities for balanced warmth and breathability. Perforated micro vents open with motion to prevent overheating and close with decreased activity to keep you warm and ready for your next move.
