Control your body's temperature this winter with Helly Hansen's H2Flow Technology- Warmer. Cooler. Lighter.

H2Flow allows you to control your body's temperature. The insulation concept uses air to provide warmth and ventilation and lets you control the airflow that cools you down when necessary.

When we talked to professional sailors, skiers and mountain guides, they told us they needed something that would help them stay warm, but was more versatile and comfortable. We had the idea of a system that could provide heat when needed, but with a high volume of mechanical ventilation so you could get rid of the heat and cool off when you warmed up.

Since heat is trapped in air pockets, we looked for designs with little pockets around the jacket, which was a completely new concept.
Through countless tests and prototypes, we realized that this indeed created a unique solution – a jacket that is Warmer. Cooler. Lighter.
