The Nike Therma-Fit AeroLayer Vest is a high-performance, lightweight insulated vest designed for active wear in cool to cold conditions. Featuring a distinctive 3D quilted baffling pattern on the front (resembling aerodynamic chevrons) for enhanced thermal efficiency and freedom of movement, it uses advanced Therma-Fit technology to trap heat while wicking moisture away from the skin. The back panel is smooth, wind-resistant fabric with a vertical zippered pocket for secure storage, and the vest includes a full-length front zipper, adjustable hem drawcord, and side zip pockets. Constructed with durable, packable nylon, it’s ideal for layering under jackets or wearing solo during training, running, or urban commuting. The minimalist black colorway ensures versatility across sporty and streetwear aesthetics. Nike’s iconic Swoosh appears subtly on the left chest and lower right hem, reinforcing brand identity without overt branding. Designed for men, this vest balances technical functionality with sleek modern styling—perfect for transitional seasons when core warmth is needed without bulk.
