"Ice vests" provide the greatest covered surface area, and can provide adequate cooling temperatures. It should be noted that a mixed modality approach (for example, core cooling and wrist cooling) has shown added benefits over the use of a singular modality.
*"The goal of cooling should be to change physiological responses, as those will have substantial effects on performance".
This is why evaporative cooling cannot provide the physiological benefit that is needed to prevent heat stress.
How to Use Oro Cool Cuffs: Insert one CoolPak into the concealed pocket of each cuff. When worn, there should be only one layer of fabric between the CoolPak and the inside of your wrist. If there is more than one laye of fabric between you and the CoolPak, flip the cuff to position the single layer against your wrist. This provides a higher impact of cooling.
