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 cheated and used larger gel packs and it worked the entire game. Working on a lot of artificial turfs during the summer temps (between 95 - 100) can be excruciating, but this product actually helps.

Works great, especially when you have multiple games in a day!

Great idea and able to keep hidden over the cooling towel hanging out over the collar of your shirt, depending on how you tight you wear you chest protector. Won’t last entire game and have to take of chest protector to change out but that is mentioned in the instructions but it helps out to cool you off for few innings. Every little bit helps in the humidity, heat and lack of breeze that happens and will keep working all day. Just stick back in cooler between games. Package came with enough that you can use one while other set is recharging.

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.
