Women's Heat-Seal Primaloft Gold Label Running Puffer Jacket

40g Primaloft Gold Insulation

Gold-series Primaloft balances premium warmth, breathability and water repellency, delivering insulation comparable to mid-to-high fill power down. It retains 95% thermal performance even when saturated. Its open fiber structure circulates air to vent moisture and keep runners dry throughout workouts.

MICROFT® Miratex High-Density Eco Functional Fabric

Outer and inner layers woven from N66 Miratex yarns provide water repellency with 5000 MVTR breathability to prevent stuffiness. Fine yarns yield a luxuriously soft touch, and N66 construction resists abrasion and tearing.

 Zoned Dynamic Warmth

Modular segmented design features 0°C grid fleece panels on high-sweat, high-ventilation zones (sides, underarms, under sleeves). Internal C4 sweat channels quickly draw perspiration to the fabric surface for evaporation, balancing warmth and airflow to boost athletic performance.

Furnace Yarn Technology

Large grid fleece lining sides, underarms and under sleeves is woven with proprietary Furnace Yarn:

• Far-Infrared Heat Boost: Volcanic mineral powder absorbs body far-infrared rays, raising skin temperature by 3.2°C in lab conditions and improving blood circulation.
• 3A Anti-Bacterial & Anti-Mite Protection: Seaweed polysaccharide suppresses >99% of E. coli and Staphylococcus aureus, with mite resistance exceeding 90%.
• Quick-Dry Warm Insulation: C4 grooved fiber maximizes surface area for heat retention; aerogel honeycomb pores deliver lightweight insulation. Virgin yarn eliminates cold dampness caused by sweat.
