Why We Love The Alt HB Hooded Jacket

When the temperature drops, finding the perfect balance between staying warm and avoiding overheating can be a challenge. That's where the Alt HB Hooded Jacket comes in. This innovative jacket combines breathability and body temperature management to provide ultimate comfort in all conditions.

Unlike traditional synthetic insulation, the Alt HB features a groundbreaking Octayarn lining that effectively removes excess heat from your body, ensuring that you stay at just the right temperature no matter how intense your activity.

While CFM ratings are typically associated with windproof garments, the Alt HB breaks the mold with its exceptional breathability. Marmot has tested the jacket and given it a rating of 50 CFM, making it as breathable as can be.

Thanks to its excellent airflow and thermal-regulating lining, the Alt HB Hooded Jacket is the perfect choice for high-output activities. It provides the necessary warmth without hindering your performance.
