Ergodyne Chill-Its Bandana

When working or exercising in hot weather this is great. A Chill-Its reusable bandana, once activated, provides cool comfort for up to 24hrs. Simply soak in cold water for 20 minutes, super absorbent acrylic polymer crystals within the band soak up water, tie it around the brow and let the slow evaporation cool you down. It can be worn with a hard hat. Cotton band ties at the back, one size fits all, and yes it really works.
