The Under Armour CG Armour Fitted Mock is a performance base layer engineered for cold-weather activity. Built around Under Armour's ColdGear® dual-layer technology, it delivers reliable warmth without bulk, keeping your core comfortable during training, golf, or any outdoor pursuit in cool conditions. The fitted silhouette moves with your body rather than against it, while smart ventilation zones and fast-drying fabric ensure you stay fresh and comfortable from warm-up to finish.
Under Armour's ColdGear® technology is the heart of this base layer. The dual-layer construction features a brushed inner surface that traps and retains body heat efficiently, keeping your core temperature stable even in cold conditions. The smooth outer surface works simultaneously to draw moisture away from your skin and push it to the surface where it evaporates quickly. This combination means you stay warm without overheating and dry without feeling clammy — a crucial balance for sustained performance in the cold.
Strategic ventilation is built in through stretch-mesh panels positioned on the back and under the arms — precisely the areas that generate the most heat during activity. These panels allow excess warmth and moisture to escape, preventing overheating during high-intensity movement while maintaining overall insulation. The stretch quality of the mesh means these zones flex naturally with your body, ensuring the ventilation panels never restrict movement or create uncomfortable pressure points.
The 4-Way Stretch fabric construction allows the material to move freely in all four directions — left, right, up, and down — mirroring the natural range of motion of the human body. Whether you are swinging a golf club, stretching for a catch, or layering up for a run, the shirt moves with you rather than pulling or bunching. This unrestricted elasticity is what makes a fitted garment genuinely comfortable rather than restrictive, and it is essential in a performance base layer designed for active use.
The fabric actively wicks sweat away from the skin and dries very rapidly, ensuring you remain comfortable and dry even during high-output activities. Complementing this, Under Armour's anti-odor technology is integrated directly into the fabric to prevent the growth of odor-causing microbes. Together, these technologies make the CG Armour Fitted Mock as suitable for an early-morning winter round of golf as it is for intensive training sessions — functional, fresh, and reliable.
The ergonomic cut has been carefully engineered to position seams away from high-abrasion areas such as the shoulders and underarms, significantly reducing the risk of chafing or skin irritation during prolonged wear. The mock neck collar adds a layer of warmth and protection around the neck that a standard crew neck cannot provide, making it especially useful in biting wind or when worn as a standalone top. The dropped, shaped hem sits neatly in place during forward bends and active movement, providing better coverage than a straight hem.
