Only one rule applies in the harshest environments of nature: adapt or die. Plants, animals, and even the terrain itself are in a constant state of adaptation. Seasonal temperature swings, wildfires, floods, droughts. When Mother Nature throws a curveball, every part of the environment must adapt, or face the consequences of stagnation. We choose the former. Through our years of hunting every environment from the high alpine to the low wetlands, we have learned the value of a clothing system that adapts. The Ambient Collection is the result of this learning. Active insulation retains heat when you are static and expels it when you are moving. Sitka Gear’s Ambient is one of the most advanced active insulation layers in the world. Don’t remain stagnant. Adapt with Sitka’s Ambient.
