Experience the ultimate in innovative warmth with our Men's Heatwave™ Body Mapped Base Layer Long Sleeve Top. This isn't just another base layer; it's a revolution in thermal technology. Featuring our #1 selling Heatwave™ technology, now extended to cover your entire body, this top delivers unparalleled warmth and moisture control. Its athletic fit, engineered with body-mapped Heatwave™ technology, ensures more warmth and rapid wicking. Anti-chafing flatlock seams, Polygiene® mesh ventilation zones, and raglan sleeves all contribute to a supremely comfortable fit during any activity.

But that's not all. We've incorporated 4-way stretch moisture control and breathable Heatwave™ material with integrated spandex, offering you the ultimate stretch, shape, and maximum comfort. The strategically placed Max Wick™ fabric enhances breathability, particularly in areas prone to overheating. For those seeking odor control, the high-performance anti-microbial mesh at key perspiration zones maintains a balanced micro-biome and effective odor management.

The genius of this top lies in its ability to provide targeted warmth to essential areas like the lower back and kidneys, thanks to the insights from body heat-map studies. This means you stay warm where it matters most without the bulk of multiple layers.
