Nike Therma-FIT AeroLayer Vest is a high-performance, lightweight insulated vest designed for active lifestyles and transitional weather. Featuring Nike's proprietary AeroLayer technology, it combines wind-resistant outer fabric with strategically quilted thermal insulation for optimal warmth-to-weight ratio without bulk. The front showcases a distinctive geometric diamond quilting pattern that enhances loft retention and airflow management, while the back uses smoother, streamlined panels for reduced drag during movement. Full-length front zipper with storm flap, two zippered hand pockets, and an internal media pocket ensure functionality and storage. Reflective Nike Swoosh logos on chest and hem improve visibility in low light. Constructed from recycled polyester shell and fill (where applicable), it aligns with Nike’s sustainability initiatives. Ideal for layering under jackets or wearing solo during mild-to-cool conditions—perfect for running, training, commuting, or casual urban wear. The slim-fit cut ensures mobility and modern aesthetic, while the hooded collar provides added neck protection. Machine washable and quick-drying for easy care.
