Zoot Ultra Icefil Dome uses ULTRAcell with Icefil that combines three technologies creating a body responsive and heat repelling cooling technology in one unique fabric. Thermal radiation blocking technology blocks infrared rays creating a 3.5F of cooling. Xylitol yarn component interacts with your body's moisture creating an additional 2F temperature drop at the skin and microdenier polyester yarns create a moisture wicking textile that pulls moisture away from your skin and helps it evaporate.
ULTRAcell AC with Icefil provides moisture activated cooling technology that responds to your sweat, reducing skin temperature up to 5.4F
