The Under Armour Authentics Mockneck ladies baselayer is built for one purpose: keeping you warm, dry, and comfortable when the temperature drops – without the bulk or the ride-up that distracts you from your activity. Constructed from UA's dual-layer ColdGear® fabric, this long-sleeve thermal top delivers an ultra-warm brushed interior next to your skin and a smooth, fast-drying exterior that faces the elements. The streamlined fitted cut, raglan sleeves, and 4-Way Stretch construction make it the ideal first layer for autumn, winter, and early spring – whether you're on the golf course, out on a run, or heading to the gym.
The heart of this baselayer is UA's proven ColdGear® dual-layer construction. The inner face is brushed to a soft, ultra-warm texture that traps your body heat close to the skin, providing genuine insulation without adding weight or stiffness. The outer face is smooth, moisture-resistant, and engineered to dry quickly after sweat transfers through from the interior. The result is a fabric that manages temperature from both sides simultaneously – warming when stationary and breathable when active – making it equally effective on the golf course, the running trail, or the ski slope.
Under Armour's 4-Way Stretch technology means the fabric extends and recovers in all four directions – vertically, horizontally, and diagonally. This matters because real-world movement is never one-dimensional: a golf swing, a yoga pose, or a morning run demands complete freedom in every plane of motion. The 87% polyester and 13% elastane blend delivers the stretch while maintaining the garment's shape wash after wash, so the baselayer continues to perform and fit like new throughout the season.
Even in cold conditions, your body generates heat during activity – and without ventilation, trapped heat becomes uncomfortable moisture. The stretch-mesh panels positioned under the arms and across the back of this baselayer provide targeted airflow exactly where your body temperature rises fastest. Unlike full-panel mesh inserts that sacrifice warmth across the whole garment, these strategic zones vent heat efficiently while leaving the main body fabric fully insulating, giving you the best of both worlds in a single layer.
The raised mock neck collar adds an important layer of warmth and wind protection around the neck – a zone often left exposed by standard crew-neck baselayers. Combined with raglan sleeves that run from collar to cuff in a continuous seam-free panel, the upper body construction eliminates pressure points at the shoulder and gives a clean, performance-ready silhouette under any outer layer. The ergonomic seam placement throughout the garment keeps stitching away from high-abrasion areas, so you can wear this baselayer all day without irritation.
