Named #1 New Product of 2020


The Cobalt™ low profile, contoured hard shell Umpire Chest Protector is a fully adjustable chest protector for all sizes and levels. Not only does it look great, it's extremely comfortable with the latest innovative air management padding, the low-profile is extremely slimming and its protective at all levels of baseball and softball. It's everything you want in an umpire chest protector and more.

With many adjustment points, you can use as much or as little of the Cobalt as you want. It's also very moldable out of the box. No need to use a hair dryer to get your hard shell to mold to where you want it. Simply bend it, shape it then let it contour to your body game after game.


  • 3.7mm thick HDPE pre-curved armor plates with hinges conform to many body shapes.
  • Removable extension adds another 3.5” of seamless protection for taller Officials.
  • Pre-curved shoulders allow CPU to hang on and not slip down the body and provide superior collarbone protection.
  • All armor plates have memory – bend them to form a custom shape.
  • Shoulders guards can move outward by 1/2 inches for larger umpires.
  • Removable shoulder gap cap for an even lower profile fit.
  • Air management system pads for maximum ventilation
  • Patented central cooling channel with removable and washable chest pads
  • The original DeltaFlex™ harness with hook ups straps located in front for easier on/off.
  • 12.5" in length and 16" with extension
  • Weight = 2.7 pounds and 3.3 pounds with extension.

This is a great umpire chest protector! Lightweight and stays in place. The pre-curved shoulders definitely help keep this protector in place along with the comfortable DeltaFlex harness. I removed the extension and the shoulder gap caps for a nice low profile look. Haven't taken a good shot to the protector yet, but I feel confident that it will do the job under fire. Very impressed so far!

Awesome Chest Protector. I really like the low profile it gives me and the protection is outstanding. My co-officials really like it too and seriously thinking about purchasing one themselves. Thank you guys again!!!

Out of the box I really was surprised at the fit. I have taken a few shots and unfazed. I have a couple things that I think need improvement. 1) The straps where they connect to the buckle. 2) The extension plate seems to be rigid in the center. Just take it off and you have an outstanding umpire chest protector.

Questions About This Product

Q: What’s the best way to clean this chest protector?
– Colby Costanzo
Treat any chest protector like you were washing your car. Remove any padding that can be removed, make up a bucket of warm water and mild soap, and use a scrub brush to apply the solution to the removed pads, then to the shell of the chest protector. Rinse with a hose or under the sink. Then let hang dry in a well ventilated room or outside. Give yourself maybe a day or two for this process to ensure the padding is dry before putting back into your gear bag.
