At Seirus, we're excited to introduce you to our innovative Women's Heatwave™ Body Mapped Base Layer Long Sleeve 1-4 Zip Top. It's not just a garment; it's a revolution in thermal technology, designed with your comfort and performance in mind. This top features an athletic fit with a convenient 1/4 zip, engineered with our exclusive Heatwave™ technology for enhanced warmth and rapid wicking. Its unique design includes anti-chafing flatlock seam construction, and strategically placed Polygiene® Mesh anti-microbial ventilation zones for focused perspiration evaporation.

Ideal for active women like you, it boasts 4-way stretch moisture control, breathable fabric integrated with spandex for maximum comfort, and ergonomically placed Max Wick™ fabric for increased breathability. Reflective accents enhance visibility, while high-performance anti-microbial mesh at key perspiration zones ensures a balanced micro-biome and odor control. This base layer leverages body heat-map studies to deliver warmth precisely where it's needed, including extra insulation for the lower back and kidneys.
