What makes the Headwind Jacket the ultimate mid layer? Its high-tech fabric and intelligent insulation. The thermal resistance (clo value, tog rating, etc.) of the insulation actually changes according to varying weather conditions. The thermal gates, or chemical micro-spaces, within the Headwind Jacket close during colder conditions for maximum thermal efficiency. As the temperature rises, the micro-spaces start to open and allow excess heat to escape.
Wear the Headwind underneath a waterproof shell for the ultimate performance layering system, regardless of work rate or weather. Wear it alone in cool, dry weather. Features:
- Zipped hand pockets
- External chest pocket
- Compresses down easily to help with stowage
