1. ADJUSTABLE, CUSTOM FIT It is important for cooling vests to fit snug to the body for optimal cooling. This cooling vest has adjustable hook and loop straps at the chest, waist and shoulders for a snug, comfortable and customized fit.
Please note: The example vest shown above is size M/L. The number and location of pack pockets varies for each size. The different vest sizes include eight (8) to twelve (12) cooling packs. See the size chart tab for more information.
If you think you are in between two sizes, order the next size up to accommodate the cooling packs. Make sure the cold packs are in the pockets when trying on the vest.
This vest is adjustable at the shoulders, chest and waist. Therefore, it will fit a large range of sizes. These measurements may help determine the best size for you.
You can exchange the size of your vest within 30 days of receiving your order as long as your vest is unused and in like-new condition. You will have to pay to ship only the vest back to us (keep your cooling packs), but Polar will ship the new size vest back to you free of charge.
"Love my Polar vest!"
Kristy R. on 10/14/2021 12:32:07 PM
Details: I have incurred several traumatic brain injuries, resulting in degenerative motor skills. Since heat is one of my symptom triggers, wearing the Polar Vest has helped a lot in avoiding episodes of debilitation when I am subjected to high outside temperatures or too much physical exertion. Plus, it's a nice ice bath for my body after exercise! Thanks, Polar Vest!

Details: My wife has had a Polar Kool Max vest for over 10 years to help her deal with the heat - she has MS. We're looking at five or six days with temps around 90 this week, and she would be stuck in the house without this cooling vest. It is invaluable at times like this.

"Polar Products is a life saver"
Tara on 8/4/2020 4:44:16 PM
Details: Polar Products is a life saver, literally! I suffer from a rare condition called Erythromelalgia. It is also known as burning man syndrome. Unfortunately, after I developed E.M. I became heat intolerant. This has posed a huge issue for me since I live in the South. At the same time I developed a condition called POTS (Postural Orthastatic Tachycardia Syndrome). Heat Intolerance is an issue for POTS too. For the last five years my late Springs and Summers as temperatures began going over 65 degre... More details

Details: Last year I suffered from the early stages of heat exhaustion driving the bus in our high temperatures and humidity in Tennessee. It was just too hot to work safely. I ordered the Polar KMVZ-KM Kool Max vest this year and it has been a game changer! I just drove my school bus for just over 2 hours in heat that started out at 110 degrees and worked its way down to 92 degrees with the windows open. When I exited the bus I still had another 45 minutes or so left on my vest. I was not even sweating!... More details

Laughing Flowers Farm on 8/30/2018 12:24:04 PM
Details: My latest discovery to help manage the Texas heat is a great cooling vest made by Polar Products. They have a variety of vests available but my husband and I invested in an adjustable vest. It has Velcro straps to hold it on and small frozen pouches that fit neatly into pockets in the vest. We've worked several hours at a time wearing these vest and they were a life send. I know, it''s another expense, but when the temperatures are over 100 degrees, it was worth the investment.
Jay H on 9/20/2016 10:21:15 AM

Robin Damato on 8/3/2015 10:50:54 AM

"Kool Max® Zipper Front Vest"
Barb Kolb on 7/14/2015 9:28:34 AM
Details: I bought this vest for my husband, who is 6'3" and wears a 3XL. He has dysautonomia, chronic migraines, and fibromyalgia. He does not handle hot weather well. He is also an automotive technician, so he works in a hot shop and often times over a hot engine. He has only been wearing the Kool Max vest for a week now, but he is absolutely in love with it. It fits him well, is comfortable to wear at work, and he is much cooler with his vest.
Judy Cervantes on 7/9/2015 5:58:17 PM
Details: This vest felt heavy when not being worn, and I thought it'd be uncomfortable. My first time wearing it was in Midwest hot humid weather. It kept me comfortably cool and I could forget I was wearing it, as it was not heavy on my body at all. I am so happy to have this vest! I can do things that the heat would make impossible to do without the vest! A life changer for persons with MS, no doubt about it.

"Perfection has a price"
James Morgan on 6/30/2015 8:18:34 PM
Details: I have found that wetting an athletic tee shirt and wearing the vest over it provides me the best cooling. Excellent size adjustability. Great, lasting cooling in all but 95 degree+ direct sunlight days, last almost two hours still, thats when a second set of packs is handy. I also plan on buying the Kool Max fashion vest for everyday use.

Mary Showalter on 6/19/2015 10:13:52 PM
Details: I do about 60 - 90 minutes of aerobic exercise a day. With the heat of summer my balance and walking at the end of exercising has been negatively impacted. Since I have purchased and used the vest during my exercising my balance and gait have greatly improved. This has been wonderful as I do not want my MS to prohibit me from the activities I have done in the past.

Angie on 6/17/2015 9:31:57 PM

Details: I work at a busy airport refueling aircraft. My job requires me to be in the heat all day with temperatures in the high 90's most of the summer, and temperatures in triple digits about fifteen days a year. I wear this vest when it gets into the triple digits, and it keeps me cool for about two hours. If I don't wear it I get the light headed and start to feel the onset of heat exhaustion after an hour. The vest is a life saver for me. It is very comfortable and adjusts very easy to fit my body. ... More details
"Not for me"
Shannon Shock on 6/8/2015 9:11:19 PM
Details: This vest can be adjusted with the velcro straps along the shoulders and waist. I am a 5' 3" woman and weight 125 but I am big on top. When I got it adjusted to fit my curves it didn't look very flattering. I already have a zip front Women's Fashion Vest that I LOVE but it only has 5 cold packs and the velcro vest in my size has 8. So I kept the ice packs and returned the velcro vest. I am going to modify my "fashion " vest and add more pockets for extra ice packs.

No one else is hot, just me. I purchased a Polar Kool Max vest and it has turned my life around.

Geoffrey K Kern on 9/3/2013 1:54:14 AM
Details: This is the best cooling vest I have owned to date, from Polar Products as well as from other companies. I wear it OUTSIDE my shirt and find it is more manageable and cools just as well as other vest. It is also flexible in that if it is not as hot I don't have to insert all of the gel packs, or, if a long period of cooling is needed, I put in half of the packs and keep the other half frozen in the carrier bag I purchased with the vest and trade the packs out hours later for extended relief.

The first time she used the cooling vest she was able to walk around the zoo with some breaks to sit down for a while and continue for the entire time (4 hours) that we were at the zoo with our family.

I bought the cooling scarf a couple of years ago and it helped some, but this year it was obvious I needed more.

"Kool Vest Keeps Seizures Down!"
Mark Moxley on 6/27/2013 11:38:10 AM
Details: Not an MS patient, but a serious stroke survivor with stroke induced epilepsy. Cooling vest helps to reduce the number of seizures in warm/hot times. I wore out my first vest and just recently bought my second. It allows me to get out of the house and actually do some small things around my house or go for short walks with my wife. Visit with neighbors outside in the Summer-many things that would be tough in the heat without the cooling vest. It really makes a difference for me!

I struggle daily to live a normal life. I have severe heat intolerance due to my syndrome due to my autonomic system failure.

But 1 day of wearing it to a outdoor event and I was trilled. You do need a t-shirt under it if wearing clothes over to hide it. I have decided to try to 'decorate' mine on the surface.

The shell of our vests is made of a cotton twill and the interior of the pack pockets has a lightweight layer of insulation for comfort and protection.
