Breathable, low-bulk midlayer for high-output mountain missions
What Our Gearhead® Experts Are Saying:
"This is the layer I grab when I’m heading out before sunrise and don’t know what the weather’s doing—it runs warm when I need it, dumps heat when I don’t, and fits under everything."
The Stio Trax Power Grid Half Zip Hoodie is purpose-built for dynamic days in the mountains. Polartec Power Grid fleece uses a raised interior pattern that traps warmth, moves moisture, and packs down small, making it an ideal midlayer for skiing, hiking, or cool-weather climbing. The streamlined hood adds extra warmth without bunching under a helmet, while flatlock seams, thumbholes, and a hidden hem pocket keep comfort and utility high. Whether layered under a shell on storm days or worn solo on crisp trail runs, it’s the kind of versatile fleece you’ll keep at the top of your gear bin.
