The WarmCube Active Aerothermal Vest is built for mountain athletes who need core warmth without bulk or overheating. Marmot’s 3D WarmCube® construction creates surrounding air channels that trap heat while still allowing airflow, delivering insulation that performs while we’re on the move.
The hybrid fill combines 700-fill Down Defender in the front and back with Primaloft® Active Evolve in the side panels, ensuring lightweight loft, moisture resistance, and breathable comfort where it matters most. A recycled polyester ripstop shell adds durability, while two hand pockets offer quick storage for essentials. Lightweight and packable, this vest transitions seamlessly from ski tours and alpine climbs to everyday layering.
