While on the job, beat the heat and cool body temperature by using our Cool Blue Towel. Our 26" x 17" cooling towel provides the latest in cooling innovations. The super-evaporative Poly Vinyl Alcohol (PVA) material holds water without feeling heavy. The secret is inside with specially-blended polymers that absorb moisture to keep you cool up to 5 hours (depending on humidity levels). This towel feels significantly cooler than ambient air. It's anti-microbial treated which helps prevent mold build-up and unwanted odors. To activate, simply soak in cool water for 2-3 minutes, then wave in the air for 10-15 seconds. To use, wrap the damp towel around your neck or hold against your forehead. It's also safe and reusable, just repeat the activation process. This towel may be machine or hand washed with a mild detergent. Store it in the provided canister.
