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.

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.

Just received the Cobalt chest protector. I have enjoyed trying different configurations. I am still looking for the perfect fit. I have a long torso so the extension looks promising. I saw some hacks about moving the buckle to the extension. I will try adding a second buckle and let you know. It looks to be a quality product. Lightweight. Should be great for those hot Louisiana summers. I am able to modify the shoulders to fit my wide frame.

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.
