Micro Grid

Our signature jersey fabric delivers warmth without weight by trapping heat efficiently while staying breathable. Designed by Polartec® to regulate body temperature, Micro Grid performs comfortably from 55° with a Micro Climate to 85° on its own.

While grid fabrics are typically reserved for thermal layers, this lightweight version is built for movement. The small air channels in the brushed grid allow heat to escape during effort, and when paired with a wind-blocking layer, those same pockets trap warmth. It’s not magic. It’s physics.
