The Women’s Polartec® Power Grid Half-Zip is engineered as a versatile performance midlayer for changing temperatures and active outdoor use. Built with Polartec® Power Grid™ fleece, the fabric’s geometric grid construction increases warmth while reducing bulk, allowing excess heat and moisture to escape during movement.
Designed to function as both a standalone layer and part of a technical layering system, the fleece delivers breathable insulation across seasons—from cool mornings on trail to cold-weather layering under outerwear.
Trizar™ warming cuffs help retain body heat at key exposure points while maintaining stretch comfort and mobility. Every garment is 100% sourced and manufactured in the United States for consistent quality and long-term durability.
