"What Our Gearhead® Experts Are Saying:""This fleece is my top choice for layering on high-output missions. It’s super light, breathable, and the grid fleece wicks moisture like a pro—plus, it fits clean under any shell or pack.""When fast and light is the mission, the Aenergy Light ML 1/2-Zip Pullover is the midlayer we reach for. Designed with Polartec® Power Grid™ fleece, this pullover balances warmth and breathability, offering next-to-skin comfort that doesn’t weigh us down. From ski tours to fall scrambles, it keeps pace without overheating. A long front zip boosts airflow on the climb, and flatlock seams reduce bulk for smooth layering. With recycled content and a bluesign®-approved build, it’s a responsibly made essential that supports our pursuit of vertical miles without compromise."
