The Nike Therma-Fit AeroLayer Vest is a high-performance, lightweight insulated vest designed for active athletes seeking core warmth without bulk. Featuring Nike’s proprietary AeroLayer technology, it combines wind-resistant outer fabric with strategically quilted baffles that trap heat efficiently while allowing breathability during movement. The front showcases a distinctive angular, chevron-style quilting pattern for enhanced thermal retention and modern aesthetic appeal, while the back uses smoother, streamlined panels for reduced drag and improved layering compatibility. Constructed with water-repellent treated fabric and a full-length YKK zipper with storm flap, it offers reliable protection in cool-to-cold conditions (5–15°C). Two zippered side pockets provide secure storage, and the interior includes a hidden media pocket with cable routing. The vest is engineered for layering over base layers or under jackets, ideal for running, training, or urban commuting. Its sleek, athletic silhouette and reflective Nike Swoosh at hem ensure visibility and style. Lightweight (approx. 280g), packable, and machine-washable, it delivers premium comfort and function for daily wear or sport-specific use in fall/winter seasons.
