Your route to the summit is determined not only by conditions on the mountain, but your choice of attire as well, and that's why the Trembler Jacket's hybrid construction is purpose-built for your technical alpine pursuits. The streamlined design offers lightweight warmth and mobility, making it ideal for snowcapped routes and exposed mountain running, whether you layer it under your favorite shell or wear it as a standalone piece. Windproof yet super-breathable, the nylon outer blocks penetrating gusts when you hike beyond the treeline, and the sleeves feature a layer of insulative fleece alongside elastic cuffs to lock in body heat. Our favorite feature is the roomy hand pocket that stows the jacket away, so you can haul it in your pack at the trailhead and break it out as you gain elevation.
