A New Dimension of Warmth

Over two years of development. Countless prototypes. Testing on three continents. This is WarmCube™.

What Is It?

Inspired by an ice tray, WarmCube multiplies the warming power of both down and synthetic insulation. It works two ways to keep you warmer than traditional down jackets, parkas, and other winter gear.

How Does It Work?

3D cubes conform to the shape of your body to trap warmth next to skin, prevent insulation from shifting, and eliminate cold spots. At the same time, the channels between each cube fill with warm air, which—unlike other down jackets—quickly builds a second source of thermal protection.

Looking to survive a polar vortex or bag your next high-altitude peak? We’ve got the warmest winter coats and insulated gear for you. Patent-pending WarmCube construction sets our down jackets, parkas, sleeping bags, and more apart from scores of other puffy coats and outdoor equipment on the market. Between each cube, there’s a channel that flexes and molds to your body, plus the space between each baffle also holds hot air. After testing in the most advanced gear lab on Earth, thermal imaging showed WarmCube air channels were the first to fill and the last to release warm air, allowing the body to efficiently generate and retain heat. As you’re out there belaying or pushing for cold summits, WarmCube will provide the protection you need.
