Athletes performing in cold weather used to have to choose: insulation or ventilation? But for optimal performance, you actually need both. With the Nike Aeroloft technology’s unique alternating zones of lofted insulation and perforated ventilation, you get lightweight warmth that still breathes.
A high-performance blend of down and synthetic insulation provides superior warmth with little weight. Zoned perforations of varying sizes allow excess heat and moisture to escape, while maintaining optimal warmth.
COMFORT ON THE RUN
Streamlined design hugs the body, reducing bulk and keeping heat closer to the skin.
REFLECTIVE, SECURE STORAGE
A reflective, zippered pocket in the back stores small items while enhancing visibility during low-light runs.
