What Our Gearhead(R) Experts Are Saying: "The Fusion Grid Hoodie is my go-to midlayer for alpine missions. It's warm but never stifling, thanks to Polartec Power Grid's breathability. I love how easily the hood fits under a helmet, and the two-way zipper makes it super practical for layering with a harness on." Designed for demanding mountain missions, the Millet Fusion Grid Hoodie is built to keep us warm, mobile, and dry through every ascent. Its Polartec(R) Power Grid(TM) fabric traps heat close to the body while efficiently wicking away moisture, creating a balance of warmth and breathability that's perfect for high-output climbs. Despite its technical performance, it packs down easily, making it a staple in our layering system for fast-moving alpine objectives. Every detail of this hoodie is fine-tuned for the mountains. The balaclava-style hood slides seamlessly under a helmet, while raglan sleeves and seamless underarms eliminate chafing from backpack straps. Two high-set zippered pockets remain accessible with a harness, and the two-way zipper allows quick venting or layering flexibility. From early-morning approaches to summit pushes, the Fusion Grid Hoodie is a lightweight powerhouse we trust for warmth, movement, and comfort in alpine environments.
