This Nike Therma-Fit ADV Running Vest is a high-performance, sleeveless outerwear piece engineered for cold-weather running and active training. Featuring a distinctive chevron-quilted construction with lightweight insulation, it provides targeted warmth without bulk, enhancing mobility and breathability during intense activity. The full-length front zipper allows for quick temperature regulation, while two zippered side pockets offer secure storage for essentials like keys or gels. Reflective accents on the shoulders improve visibility in low-light conditions. The interior collar tag clearly displays 'NIKE RUNNING' and 'THERMA-FIT ADV', confirming its advanced thermal regulation technology—designed to retain body heat while wicking moisture away. Constructed from durable, wind-resistant synthetic fabric with a smooth, slightly matte finish, the vest maintains shape and resists abrasion. A subtle white Nike Swoosh at the lower right hem adds brand identity without compromising minimalist sport aesthetic. Ideal for layering over base layers in fall/winter runs, gym sessions, or pre/post-workout warm-ups. Its slim, athletic fit ensures no drag or flapping during motion, making it a functional staple for serious runners and fitness enthusiasts seeking technical performance in a sleek, modern silhouette.
