Evolved Air 1/2-Zip Midlayer delivers breathable warmth and sustainable performance for all-day adventures
What Our Gearhead® Experts Are Saying:
"This is one of my favorite midlayers for cool-weather hiking and ski touring. The grid fleece traps heat without feeling stuffy, and the half-zip lets me dump heat fast on the climb. I also love that it’s fully recycled and mono-material—it’s warm, functional, and made responsibly."
Designed for active days in the mountains or city alike, the Helly Hansen Evolved Air 1/2-Zip Midlayer balances warmth, breathability, and sustainability in one sleek package. Its grid fleece construction traps body heat while promoting airflow, ensuring we stay comfortable during high-output activity and quick temperature shifts. The recycled polyester fabric wicks moisture efficiently and feels soft against the skin, making this midlayer a reliable go-to in any layering system.
A high protective collar and adjustable hem seal in warmth, while the YKK® half-zip adds easy ventilation and layering versatility. A zippered chest pocket secures small essentials, and the embroidered Helly Hansen logo nods to the brand’s alpine heritage. Built as a bluesign® certified mono-material garment, the Evolved Air 1/2-Zip is designed not only for performance in the outdoors but also for a cleaner, more circular future.
