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.

Right out of the box!!!!! If you are a small frame umpire like me and looking for a real low profile chest protector, this is the one!!! I am 5' 4" 140 pounds guy. I have tried many umpire chest protectors, including the Wilson Gold. Obviously, I looked like a NFL linebacker. I loved the protection, but hated the look. I was a little worry, I was going to spend more money and not look the way a professional should. To my surprise, the new All-Star Cobalt umpire chest protector fitted perfectly after taking (very easily) the extension off. It feels very light and looks awesome. I am very happy with the purchase and will recommend it to all of my fellow umpires.

Only giving 4.5 stars because I haven't actually used it in a game yet. Overall impressions:1) Incredibly adjustable 2) Super professional look and profile 3) Robust yet thin! Check out my comparison video: https://youtu.be/6Yp1qeF5fKI Awesome umpire chest protector. Can't wait to use it in a game!

Excellent quality. Easy to adjust based on the user's needs. Only felt the impact of a baseball, with good coverage. Being average size, I removed the middle shoulder cap. Kept the extension, but it doesn't look bulky and doesn't noticeably add to the weight.
