The original Maximo CoolVest features elastic side panels that connect the front of the vest to the back. It also features belt loops which keep the wrap-belt extensions in place. 

The Maximo Gen II is held snug to the body with broad belt flaps that create the sides of the garment when wrapped around the body. This allows for complete flexability in sizing, as the belt creates the side closure -- versus the elastic side panels. 

Sizing for Maximo Original varies from our Gen II, so please refer to the size chart before ordering.

Multiple Sclerosis Patient Needed Cooling Vest

I was recently diagnosed with Multiple Sclerosis and need to keep my core cool to reduce MS attacks and severity. I live in Southern California where it gets really hot and summer temps can be brutal. I also live on a ranch and the animals must be taken care of regardless of how hot it is. I looked at cheaper vests but all they were was material soaked in water and put on for an evaporative effect. Not any better than taking off my t shirt and getting it wet on the wash rack at the barn and putting it on. I found this and decided to try it since it had actual frozen material held close to the body. We have had 90+ degree temps the last two days with 35-60 % humidity so a pretty good test environment. I had frozen the gel packs and inserted into the vest and put on with my t shirt underneath to go out and feed and water the animals. I did stay much cooler than without the vest and wasn’t sweating up a storm or getting dizzy in the heat. But after 1 hour the gel packs were thawing out about half way, but still keeping me cool. When I returned to the house I just stuck the whole vest in the chest freezer so I can easily grab it before going out knowing it will be good to go. If you need cooling power for more than a couple of hours you will need additional gel packs to swap out. This will work for MS patients for 2 hrs or less. If you want to do outside activities for longer you need cooling gel inserts front and back. So for riding and driving the mules and donkeys I bought a Glacier Tech vest that holds frozen cooling gel packets both front and back and will last up to 4 hrs no problem. It is also heavier and bulkier and of course costs more. MS patient’s internal thermometer is broken and we are always hot and overheat easily. So we must have a way to keep cool outside or we can’t go outside. This vest would be great for gardening, walks, short errand runs etc for MS patients as well as normal people looking for some heat relief. If you need to use it on the job outside buy several gel cooling packs to swap out throughout the day. I found the gel packs expand much more easily in warm water in the sink, submerged under a dinner plate for a couple hours. All expanded no problem.


The photos are misleading. Once the ice packs are added this is very bulky and looks like a life vest especially if you have breasts. I bought this for equestrian sports. You could only use after you have taken care of your horse. Once you can put it on, it works fantastic. But I went off the thin photo and was disappointed not being able to wear . The ice packs are bumpy so if you fall wearing this, it will hurt.

Nice cooling vest

I ordered this on advice from others with MS to see if it would help with my heat intolerance. It helped greatly. I used it for mowing our lawn on an upper 80's day.
I mowed for about an hour and the cooling packs were still more than 1/2 frozen and I was still comfortable. It wore nicely and was not restrictive at all.
Definitely would recommend this.

Helped During the Heat Dome

I have MS and heat exacerbates my symptoms. While I initially purchased this vest to help keep cool while exercising outside during the summer, it proved invaluable to helping keep cool during the 'heat dome' event that his the west coast during the end of June, both when I was inside or outside!

Its minimal size and shape allows you to move freely when wearing it (even when wearing a back- or water-pack over top), but the full back ice pack still keeps you cool.

I highly recommend it for those looking for a lightweight and unobstructive way to keep cool in the heat.

Comfort found in a vest!

my experience has been great. From the first call to ask questions about the product. Order fulfilled in no time at all. wearing the vest has been wonderful, helping to keep my core temperature in control so I can be active outdoors for much longer. The zipper is easy for me to use too. This summer is going to be great!
