Keep your cool, with some added arm protection, on sweltering days in the field in this ultra-light, sun-shielding tee.  Employing our Omni-Freeze advanced cooling, this high-tech basic features special flat yarns that transmit heat faster and therefore actually feel cooler to the touch against your skin. The fabric also wicks sweat and shields your skin from UV rays with UPF 30 sun protection. Long sleeves help keep you covered, and add to your camo factor.
