Polartec^®Power Air^™is a new revolutionary knit construction that encapsulates air to retain warmth and reduce microfiber shedding.

The result is a performance fabric with advanced thermal efficiency that sheds up to 5x less than other premium mid-layer fabrics. And while all fabrics will shed fibers over time, Polartec^®Power Air^™is a step forward in reducing the environmental impact of what we make and wear.

WARM MORE. SHED LESS.

ABOUT POWER AIR^™TECHNOLOGY

By engineering a way to encapsulate fibers, Polartec^®Power Air^™is changing how insulation fabrics perform over their lifetime.

This new fabric construction encases internal yarns, creating individual air pockets that capture body warmth. The surrounding knit casing also serves as a supporting barrier, preventing loose microfibers from shedding out into the environment. Power Air's two distinct surfaces provide wider design versatility than most insulation to prevent pilling and promote easy layering with other materials.
