Polartec® Power Shield O2®

Wind-blocking fabric that moves and breathes with you.

Polartec® Power Shield O2® is the outer layer to wear when you need enhanced breathability. Its specially constructed face precisely controls airflow to block 96% of wind while allowing the remaining 4% to circulate within the fabric, maximizing moisture vapor transmission. All Polartec® Power Shield O2® garments are finished with a Durable Water Repellent (DWR) to shed precipitation and feature spandex or mechanical stretch for freedom of movement.
