Stay cool on the job with cooling headwear and liners. On a 90 degree day, a cooling hard hat liner may be one of a construction worker’s favorite hard hat accessories. Cooling towels, sun hats with specialty cooling liners and more keep landscapers, gardeners, sports fans, golfers, fishermen and anyone who works or plays outdoors nice and cool in the hot sun. Items may vary by size, material, color, standards and specifications, among other considerations. For more, see our headbands and sweatbands.
