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.

I think the Cobalt combines the best features of the Gold, Platinum, System 7, and even the Holy Grail of the Power. Then adds padding that they actually put a lot of thought and testing into. Add to that the adjustability of it, and you have a giant leap forward in our protection.

I have used just many different chest protectors over the years. Original Douglass WV, Gold, Platinum, Honig's K1, F3, Diamond hardshell, All-Star System 7, and even my current favorite Champion P215. All very good chest protectors in their own right. I have followed and anticipated this All-Star Cobalt for some time now. After watching the webcast a month or so ago, and understanding the R&D that went into this chest protector, I had to give it a try. I was not disappointed. The low profile look, the ability to customize to my liking as well as the quality, have me looking forward to the first game I can use it; I live in California currently. I have played around with different adjustments and I do have this rig now dialed in to fit like a comfortable glove. Thanks Ump-Attire.com for the solid service as well as taking the time to provide the webcast with All-Star. It really did help me make up my mind.

Wanted to give this 5 Stars, but can’t. The lower abdomen extension has these unremovable protruding (and unnecessary) Love Handle wings that stick out, look weird, and catch my forearms. The center part of the lower abdominal extension is perfect, as is the rest of the chest protector. It’s light on the body, facilitates movement, breathes well, is easy to adjust, fits snuggly, is low profile for a hard shell, is comfortable, is easy to put on, and gives “Didn’t even feel it!” protection for hard shots to the body. If they fixed those annoying love handle wings, I’d give this 6 stars if I could, the rest of this protector is that good.
