Nike Therma FIT ADV Repel AeroLoft Down Singlet - Yellow - L

The jacket provides excellent warmth for cool to cold weather due to its down and synthetic insulation. For extreme sub-zero conditions, layering may be necessary.

Machine wash cold with like colors using a small amount of liquid detergent. Avoid fabric softener and bleach. Crucially, tumble dry on low heat with tennis balls to restore the down's loft.

Therma FIT ADV refers to Nike's advanced thermal technology, combining materials and construction techniques to help regulate body temperature and keep you warm.

The jacket features a water-repellent woven outer fabric that can handle light showers, snow, sleet, and hail. For prolonged heavy rain, a waterproof outer shell might be more suitable.

The reflective elements are designed to be durable with proper care. Avoid excessive abrasion and follow the washing instructions to maintain their reflectivity.

Down insulation at the chest offers superior warmth-to-weight ratio for core heat. Synthetic insulation used elsewhere provides reliable warmth even when damp and is generally easier to care for.

Ensure the jacket is completely dry and tumble dry on low heat with clean tennis balls to help break up clumps and restore loft to the down insulation.

Clean the jacket according to care instructions. Consider using a specialized water-repellent spray suitable for down and synthetic insulated outerwear after cleaning.

Gently try to move the zipper. Apply a small amount of graphite (from a pencil lead) or a specialized zipper lubricant to the teeth and move the zipper up and down several times.
