Helly Hansen H1 Pro Lifa Seamless 1/2 Zip Top

The H1 Pro Lifa top uses thermal mapping and Lifa technologies to precisely control your body temperature, giving you the right amount of warmth in high-intensity scenarios. The H1 Pro Lifa top also features a half zipper, laser-cut holes in your hottest areas, and a snug, high-performance fit.

Stay warm and comfortable without overheating thanks to the H1 Pro Lifa top from Helly Hansen. Constructed using thermal mapping and Helly Hansen's signature Lifa technology, the top works tirelessly to ensure you remain at the optimum temperature to help you perform at your maximum level for longer. The mapping technology precisely controls your body temperature, affording you the perfect amount of warmth for all your high-intensity activities. Additionally, Lifa works by actively and efficiently wicking away the build-up of excess sweat and moisture, leaving your skin feeling dry and comfortable as you strive for the best results and performance. Furthermore, cool air is encouraged to circulate, creating a drier, healthier environment for your skin to thrive.

Extra sources of ventilation are provided by the half zip, allowing you to lower the zip to improve air circulation on warmer days. Conversely, the zip can be pulled up to the top to retain warmth when the temperature begins to drop. Laser-cut holes have been incorporated into the design of the garment for the aforementioned additional source of ventilation. A multi-fabric seamless construction adds resilience and durability without sacrificing the comfort of the garment. The seamless design of the top also prevents friction and irritation such as chafing. Merino wool adds a soft, next-to-skin feel to improve the comfort.
