Polartec Fabric:
- New fabric construction encases internal yarns, creating individual air pockets that capture body warmth.
- 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.
