The weather in the high alpine is anything but predictable. Sunshine at the trailhead provides little guarantee that there will be sunshine at the summit, and that's why we pack along our Marmot Highlander Down Hooded Jacket. This lightweight down hoodie provides incredible insulation courtesy of 700-fill down, and the Pertex Quantum membrane improves thermal efficiency while blocking out the wind, so we can venture freely above the treeline. The face fabric is water-resistant to shed light rain, and the Down Defender water-resistant treatment ensures the down insulation stays lofty in damp conditions. The elastic-bound hood, hem, and cuffs seal in warmth as temperatures drop, and help keep the jacket firmly in place while we conquer our bucket-list trails.
