Avoid the need to pause and swap layers during summit pushes with this versatile and highly breathable synthetic insulated jacket. It is engineered for dynamic mountain use, blending PrimaLoft® Gold Active+ insulation — which actively balances warmth and breathability — with low-profile Thermic™ stretch fleece side panels that provide exceptional freedom of movement and make layering a breeze. The Pertex® Quantum Air fabric offers wind resistance without compromising airflow, adapting to changing intensity levels and keeping the wearer comfortable through shifting conditions. Lightweight and easily packable, this active insulation piece functions seamlessly as either a warm midlayer or a technical outer layer, from early morning starts to high-altitude efforts.
