Your Kul Lite Rider and/or Runner cooling vest is activated with water. You will want to:
1 - Soak the vest in water for 15 to 45 minutes. We usually put the vest in a gallon zip-tight bag with water at home before driving to the location.
For Runner models, and cool mornings, you can use warm/hot water.
On average warm days, you can use room temperature water.
On extremely hot days, you can use cool water.
2 - Lightly squeeze out excess water.
3 - Put the vest against your body and zip.
4 – Adjust the side strap slightly loose.
5 - Place a breathable outer shirt over the vest.
For indoors, use warm/hot water. The vest will not shock the body, it will start evaporation and cool to ideal temperature within a few minutes.
On hot days, you can use room temperature or cool water. It will be a bit of a shock, but the vest will adjust to the ideal temperature in a few minutes.
Be sure to hand wash and AIR DRY your Kul Lite after every use. For faster drying time, hang your Kul Lite inside out.
