Description
Under Armour Authentics Mockneck women's baselayer, black
Nobody likes it — that stiff, distracting feeling you get when you are out in the cold. The Under Armour Women's ColdGear® Authentics Mock Neck Baselayer is engineered to eliminate exactly that. Built from a dual-layer ColdGear® fabric that is smooth, soft, and durable, it keeps you warm and dry without adding bulk or riding up, so nothing stands between you and your best performance all season long. With raglan sleeves and 4-Way Stretch technology for unrestricted movement, this is the perfect first layer for everything from autumn golf rounds to early spring mornings.
Key Features
- Dual-Layer ColdGear® Fabric: Ultra-warm brushed interior paired with a smooth, fast-drying exterior keeps you insulated without bulk.
- Moisture-Wicking Performance: The fabric wicks sweat away from the skin and dries remarkably fast, keeping you comfortable throughout any activity.
- Anti-Odor Technology: Built-in anti-odor technology prevents the growth of odor-causing microbes, keeping the garment fresher for longer.
- Stretch-Mesh Underarm Panels: Strategic mesh panels under the arms deliver targeted ventilation precisely where your body heats up most.
- 4-Way Stretch Construction: The fabric stretches in every direction to match your body's movement, never restricting your swing or stride.
- Mock Neck Collar: The raised mock neck provides extra coverage and warmth around the neck and chin area.
- Raglan Sleeves: Raglan-cut sleeves enhance freedom of movement and create a streamlined, flattering silhouette.
- Fitted Streamlined Cut: Designed to fit like a second skin — not too tight, not too loose — so it layers seamlessly under any outer garment.
- Ergonomic Seam Placement: Strategic seam positioning keeps seams away from high-abrasion areas for maximum comfort during extended wear.
Technology in Detail
ColdGear® Dual-Layer Fabric
The heart of this baselayer is Under Armour's signature ColdGear® dual-layer construction. The ultra-warm, brushed interior acts as an insulating cocoon, trapping body heat close to the skin, while the smooth exterior repels moisture and dries at an impressive speed. Unlike traditional thermal fabrics that can feel heavy or stiff in cold conditions, ColdGear® stays lightweight and flexible regardless of the temperature. The result is a garment that genuinely feels like a second skin — warm, dry, and totally unobtrusive whether you wear it alone or as a foundation layer beneath a midlayer or jacket.
4-Way Stretch Construction
Cold-weather gear that restricts your movement is worse than useless — it actively hurts performance. Under Armour's 4-Way Stretch technology ensures the Authentics Mockneck moves with you in every direction, whether you are mid-swing on the fairway, reaching overhead in the gym, or layering up for a winter run. The stretch is evenly distributed across the fabric so there are no tight spots, no pulling at the shoulders, and no bunching at the elbows. Combined with the raglan sleeve cut, this baselayer offers a level of unrestricted mobility that makes you forget you are even wearing a thermal layer.
Stretch-Mesh Underarm Ventilation Panels
Warmth should never come at the cost of breathability. The Authentics Mockneck solves this classic cold-weather dilemma with strategically placed stretch-mesh panels positioned under each arm — exactly where the body generates the most heat during physical activity. These panels allow warm, moist air to escape before it builds up and causes discomfort, while the rest of the garment maintains its insulating warmth everywhere else. The effect is a smart thermal balance: you stay warm across your core and extremities, but never overheat or feel clammy during vigorous movement.
Mock Neck & Anti-Odor Technology
The tall mock neck collar is one of the most practical design features on this baselayer, extending well above the collarbone to shield the sensitive neck area from cold air and wind chill — a common oversight in standard crew-neck thermal tops. Paired with this physical protection is Under Armour's anti-odor technology, which is integrated directly into the fabric fibres. This technology actively inhibits the growth of odor-causing bacteria, meaning the garment stays fresher session after session, wash after wash. Together, these two features make the Authentics Mockneck a dependable, long-lasting cold-weather essential.
