Adaptive warmth for the margins of the season. Built for long ascents, pre-dawn starts, and cool descents when sweat and weather fluctuate. Breathable, hydrophobic insulation that keeps you dry through movement and warm through moments of pause. Wear it alone, over your favorite base layer, or under a shell when air sharpens.
