PhaseCore Cooling Elements are body-heat activated when skin temperature becomes warmer than 82°F. As the elements absorb heat from the body, they provide a gradual 72°F cooling effect that can last up to four hours (depending on body type, level of activity, and working environment). PhaseCore Cooling Elements do not over cool the body, nor will they prevent sweating or cause shivering.

Yes! Placing a layer of clothing over the vest helps insulate from the surrounding air, keeping more of the cold inside to cool your body.

If storing your PhaseCore Cooling Vest with your Cooling Elements, store in a cool, dry place. Do NOT store vests with elements in temperatures above 135°F, like a hot car. If elements are stored in temperatures above the activation point (82°F), the high heat will reduce the number of times the Elements can be recharged and they will require recharge before use.

Yes! PhaseCore Cooling Vests have been known to help individuals with Multiple Sclerosis return to daily activity with little risk of over-heating. PhaseCore Cooling Vests have been featured by organizations like ActiveMSers.org and MSWorld.org. Take a look at what some of our MS customers have had to say:

“I was diagnosed with MS in 2013 and heat/humidity is a particular challenge for me. My vest has literally made the difference between time outside during the summer and being trapped in my home. My vest allows me to participate in life once the weather gets hot”

PhaseCore Vest Comparison


Every year, hundreds of workers, soldiers, responders, athletes, and other individuals suffer heat-related illnesses while active in periods of high temperatures. Virtually all these incidents could be prevented with proper training and equipment.

Most consumer grade cooling vests use water packs or gel packs which melt quickly and are heavy to wear. They can restrict your movements which is not good when your safety and the lives of others may depend on your ability to move.

PhaseCore Cooling Vests will not over cool the body and eliminate risk of cold shock.
