What Our Gearhead® Experts Are Saying: "I bring the Power Grid Half-Zip on almost every trip—it’s insanely breathable, layers well under a shell, and keeps me dry even when I’m working hard. Whether I’m skinning uphill or backpacking in shoulder season, it’s one of the most reliable midlayers I’ve owned." We count on the Mountain Hardwear Polartec Power Grid Half-Zip Jacket as a go-to midlayer for everything from alpine climbs to multi-day treks. Designed with Polartec’s advanced grid fleece, it balances warmth and breathability better than traditional insulation, keeping us dry and comfortable when we’re pushing hard in cold conditions. Whether we’re booting up icy gullies or backpacking under shifting skies, this piece always earns its spot in our pack. Its streamlined design features stretch-knit side panels for improved mobility, a chest zip pocket for quick storage, and thumbholes at the cuffs for secure layering. Recycled content helps reduce its impact, while reflective details add visibility during late returns to the trailhead. Simple, technical, and ultra-functional, this half-zip is an essential part of our cold-weather layering system.
