Wrap some coolness into your umpire chest protector with the KoolBlue's Cooling System. It helps baseball and softball umpires stay cool during those hot summer days with Thermafreeze ice packs strapped onto your chest protector in a pouch with elastic straps.

This is the first prototype designed and crafted by Indiana umpire Brad Finken.


  • Compatible with all umpire chest protectors
  • 10.5" x 8.5" cloth pouch
  • Elastic straps with Velcro attachment
  • 4 Thermafreeze reusable ice packs included


  • Submerge or soak the soft side of Thermafreeze ice packs
  • Wipe off excess water and place Thermafreeze packs into freezer
  • Bring to game in a cooler
  • Insert frozen ice packs in KoolBlues pouch at game site
    • 2 at a time is recommended by the manufacturer
  • Place KoolBlues pouch on the inside of your umpire chest protector with logo facing outward
  • Attach pouch in place with elastic straps around the front of your chest protector

Note: Ice sheets are not designed to stay cold for the entire game. Body temperature and outside ambient temperature are all factors in how long the ice sheets stay cold.

I've now used my KoolBlues in temps up to 112 degrees here in Arizona, and yes, it definitely helps, albeit for a limited time as expected. For me, in those temps, the cold feeling lasted roughly about hour total, which was maybe 2-3 innings into the game (it's already on for at least 20 minutes of pregame). The one thing I did notice was that if the smooth sides (versus the rough side) of the ice packs face you inside the pouch, the "cold/cool" feeling lasted a bit longer. Not much you can do about these packs in crazy temps like we get here in the desert, but every little bit helps.

It works. Not a silver bullet, but I would 100% rather have it than not. No doubt. I don't like the heat once it gets over 90 degrees. Been using it ever since I didn't prepare and found out the hard way what some of the symptoms of heat exhaustion/ heat stress are when working the plate in 94 degree temps and above. It helps drop your body temp, and shortens the time exposed to the heat. Won't last a full game, probably will last until the mid 3rd or 4th inning. You can fit multiple sheets in the pouch to help lengthen the time and feel it even more than when you just use 1 sheet. Solid heat management tool and I strongly recommend it. It's not like putting a neck gator on and having it warm in 5-10 minutes. This product will help you work in extreme heat.

Another great cryo-option to have as umpires to help us beat the heat. This item may appear bulky in the photos, but in reality it is very thin and you will not notice any difference when wearing it under your CP. But you will notice the coolness and comfort that it will bring you on those hot days. Even if it doesn't last an entire game, you will be very glad you have it while it lasts. You can always buy more cold packs online and change them out between games if you wanted. I think you could also wear this in the field if you really wanted too. It's very thin and not bulky at all.

Questions About This Product

Q: I have already purchased this product and absolutely love it but my one concern is the material that's inside to help it freeze is coming out a little bit more every time I use it. Can you tell me how to keep that from happening?
– Michael Almony

I assume a small rupture has occurred in one of the Therma-Freeze pockets. Not much can be done to repair this pocket since the water is trapped inside. Reducing the amount of water initially filled within the Therma-Freeze will reduce the tension at the seams and reduce the chance of a rupture.
