The evaporative MX cooling vest is designed to cool the wearer during outdoor sporting activities in hot weather conditions. ? This is achieved through the garment?s water management system, which uses an exclusive polymer embedded material that has been specifically designed to absorb and slowly release water within the multi-layered fabric, significantly enhancing the body?s ability to stay cool. ? How to use: Simply submerge the garment in water for 5-10 minutes, and then remove excess water by gently squeezing the vest before use.  The vest will remain hydrated for several hours and can be rehydrated as needed.

SIZING TIP- order the same size you would order in a tight fitting t-shirt.
