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
  • Keep them flat in the Freezer at all times.
  • Bring to game in a cooler
  • Insert frozen ice packs in KoolBlues pouch at game site
  • 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.

We just had a short run of warm weather and this thing was amazing. I would definitely recommend it to anybody to help you with those long hot games.

This works great. Keeps you cool for a game, but as you use it, a slimy/sticky residue will form on the porous side of the pack.

They are better than nothing in the heat. I work mostly in high humidity and average 90 degree temps. in summer. They last about an hour at most so I bought 2 sets since I average 4-6 games a day at times. The downside is: 1) When freezing the packs make sure they are not wet so that they don’t freeze to other items in freezer, the packs will stick to other items and tear apart when you try to separate them releasing jell ruining the packs. 2) I believe the price is high considering the quality of this product. To me they don’t seam they will last more than a year or two. 3) Again, they do help. If you do moderate amounts of ball and only work a game or two in the extreme heat, then this product will work for you. Buy extras if you do high volumes of games per year.

Questions About This Product

Q: I noticed you used it with a larger protector. I wear a more narrow protector. Do you feel that with the narrow lower protection, this product will attach with no problem?
– Kenneth Fredericksen

The KoolBlues is 27 inches in total length with a 4 3/4 inch section of Velcro on an 8 inch elastic strap on either side of the ice pack pocket. With Free Returns*, there is no risk in trying this Cooling System on for fit at home.
