What Our Gearhead® Experts Are Saying: "I take the Quantum Hybrid Hoodie on cold-weather tours, shoulder-season hikes, and early-morning rides because it checks every box—warm where you need it, breathable everywhere else. The merino blend manages moisture amazingly, and the Lyoloft front panel blocks wind on exposed ridges. The hood fits under a helmet, it layers cleanly, and the comfort is next level."We trust the Merino Blend Quantum Hybrid Long Sleeve Zip Hoodie when temperatures drop and our route demands a midlayer that adapts seamlessly to changing effort and terrain. The breathable merino blend regulates heat, resists odor, and stays comfortable during long pushes, while the plant-based Lyoloft insulated front panel boosts warmth and blocks wind in exposed alpine zones. Built for technical travel, the under-helmet hood adds low-profile protection without restricting movement, and raglan sleeves support fluid mobility during climbs, ski touring transitions, or brisk morning trail miles. Alpine hand pockets warm cold fingers, the two-way zipper fine-tunes ventilation, and the hybrid design slides easily under shells or over baselayers. This hoodie feels purpose-built for cold-weather mountain pursuits, offering steady warmth without sacrificing breathability.
