SEIRUS HEATWAVE SKULL LINER

Seirus Heatwave Skull Liner

Engineered with dual-stage Heatwave kinetic thermal reflection technology, this technical skull liner reflects body heat while amplifying warmth up to four degrees. The ultra-thin stretch fabric contours to the head for an ergonomic fit that fits under helmets and hoods without creating pressure points or adding bulk. Integrated moisture-wicking properties pull sweat away from the skin to regulate temperature and maintain dry comfort during high-output cold-weather activities.

Designed for performance and comfort, the flatlock seam construction minimizes friction and prevents chafing against the skin. The full-coverage cut extends over the ears and forehead to shield critical areas from wind exposure and frigid drafts. Quick-drying fabric properties ensure rapid evaporation during intense exertion, keeping the head warm and regulated throughout active winter pursuits.
