UA Packaged Base Crew 2.0

The Under Armour Packaged Base Crew 2.0 is a cold-weather base layer designed for tactical professionals, outdoor enthusiasts, and athletes who demand reliable thermal protection during moderate activity in frigid conditions. This crew-neck base layer serves as a foundational layer system, engineered to provide insulation without the bulk of traditional long underwear. Whether you're conducting extended outdoor operations, winter training, or high-altitude missions, the UA Packaged Base Crew 2.0 delivers the thermal retention needed to maintain core body temperature and performance in unforgiving environments.

Built with Under Armour's proprietary heat-trapping pattern technology, this base layer strategically channels body heat and moisture management without adding excessive material weight. The construction uses advanced synthetic fibers that excel at retaining warmth while remaining breathable, allowing sweat and moisture to escape during activity transitions. At just 0.45 lbs, the UA Packaged Base Crew 2.0 maintains a slim profile that layers seamlessly beneath tactical gear, combat uniforms, or conventional outerwear. The crew neckline provides full neck coverage for enhanced thermal protection, while the form-fitting design ensures unrestricted mobility during dynamic movement.

This base layer is ideal for military personnel, law enforcement, winter athletes, and anyone requiring dependable thermal layers for extended cold-weather exposure. The XS size accommodates smaller frames and youth applications, making it suitable for specialized units with varied personnel requirements. The UA Packaged Base Crew 2.0 integrates effectively with standard load-bearing equipment, body armor systems, and layering protocols without compromising fit or thermal efficiency. Compatible with all standard tactical uniforms and conventional cold-weather apparel, it serves as an essential foundation for multi-layer cold-weather systems used in training, deployment, and professional outdoor environments.
