WarmCube Active Aerothermal Vest delivers breathable core warmth for active layering
What Our Gearhead® Experts Are Saying:
"This vest is awesome for ski touring and layering—it keeps my core warm without making me overheat. The WarmCube channels really do a great job of balancing warmth and breathability. I throw it over a baselayer for climbs or under a shell when the weather turns."
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.

Love this WarmCube Vest!
[This review was collected as part of a promotion.] This WarmCube vest rocks. It is a great addition to your WarmCube line of products. Light enough on warmer days, but also perfect for cool fall days, with its combination of down and PrimaLoft filling. The acai berry color is a beautiful shade of cranberry red! The vest does run on the large size, (quite large arm holes). My WarmCube jackets are a size S, and I ordered a S in the vest. I returned it and reordered it in an XS and it fit perfectly. I am 5'6" and weigh 115 lbs for reference.
