The Chilly Mini Cooling Wrap absorbs sweat and keeps you cool during a tough workout, a rough climb, a hard run, or any strenuous outdoor or indoor activity. It's reinforced with a tough athletic mesh for years of use. To activate, rinse Chilly Mini Cooling Wrap with warm water before using the first time. Keeping your Chilly Mini wet allows moisture to evaporate and continue cooling for hours. If the Chilly Mini begins to dry out , simply re-wet. Store the nature-friendly and biodegradable Chilly Pad in the original packaging.
