HEAT-OUT Helmet Liner

HEAT OUT base-layer garments utilize cutting-edge textile technology for effective temperature regulation and perspiration management -with outstanding stretch & recovery- to provide maximum comfort in warm weather conditions. A precise blend of 60% nylon, 35% polyester and 5% spandex fibers ensures dynamic fit and comfort with essential properties to enhance riding comfort. The moisture wicking properties draw perspiration away from the skin and assist in rapid evaporation into the surrounding air, thus keeping you cooler during periods of exertion or when external temperatures are high. Extraordinary stretch and recovery is achieved with multi-directional spandex fibers throughout for an optimal balance of close-fit and complete freedom-of-movement. An ANTI-MICROBIAL treatment helps to eliminate odor-producing bacteria generated during perspiration, keeping you refreshed during periods of activity and rest. Revolutionary HEAT OUT base-layer garments will enhance your riding experience. Get in to HEAT OUT!


  • Hi-Tech Fabric blend wicks perspiration
  • Full stretch and recovery for dynamic freedom-of-movement
  • Anti-microbial treatment reduces odor
  • Flat Seam construction layers comfortably

To extend the life of your Heat-Out Base Layers, machine wash cold and hang to dry. Dry cleaning, use of bleach, and tumble drying are not recommended.

Keeps the Heat out
Cool liner. Keeps my head cool when riding. Temperatures in mid to upper 90s and kept my head cool. I actually use it under a baseball catcher's helmet too when it is 90 and high humidity. Works awesome. I've been looking for one of these

One horrible part.....
The price is great but the band or hem around it is too thick and became uncomfortable. I would look for a different one that is smooth and without a welted band.
