Because minus temps don’t care how tough you are.

This is the serious stuff — expedition-weight parkas built for 14,000’ camps, polar basecamps, and summit pushes in brutal cold. Whether it’s high-loft down or synthetic fill engineered for wet environments, these layers are designed to trap heat and stay reliable when conditions are anything but. Trusted by Rainier, Denali, and Everest guides alike, these parkas aren’t for walking around town — unless your town is on a glacier.
