Nike Sports Zipper hooded Windproof Jacket - Black - L

The jacket is made of 100% Polyester, providing windproof and durable qualities.

This jacket is primarily designed for wind protection and athletic activity. For very cold weather, it is best used as an outer layer over insulating clothing.

The jacket is available in size L. Refer to Nike's standard sizing chart for men's apparel to ensure the best fit for your athletic needs.

While designed for athletic activities, its sleek black design can be incorporated into casual wear, especially for active lifestyles or cooler, breezy days.

Machine wash cold with like colors, use non-chlorine bleach if needed, and tumble dry on low heat. Avoid dry cleaning.

It means the fabric is designed to block wind from passing through it, reducing wind chill and helping to maintain body temperature during outdoor activities.

Gently pull the zipper up and down. If it continues to stick, apply a small amount of graphite (from a pencil tip) or wax along the zipper teeth.

This is normal during intense activity due to perspiration. Ensure the zipper is open slightly for better ventilation. The polyester material wicks moisture but can feel damp if sweat production is high.

Check the jacket for any tears or holes in the fabric. Ensure all seams are intact. Over time, heavy wear might slightly reduce effectiveness, but the core windproof properties should remain.
