Great Fit, comfortable, light weight...I'm confident with it.

I was lucky enough to get this second-hand off another umpire who purchased this from Ump-Attire.com. He shipped it to me in the Ump-Attire.com box it came in. I have to say, this is by far the best umpire chest protector I have used to date. It fits tight. It breathes. I can move it. I don't look like a linebacker like I did with my Wilson West Vest Platinum. It covers more area. I am 5'8", 235 lbs and this feels like a second skin.

Best chest protector I have had as a umpire. Really comfortable and very solid. You can’t hardly feel when you get struck with a baseball. All around great chest protector.

Questions About This Product

Q: Does this chest protector offer biceps extra protectors/pads? I see that arm protection is quite limited.
– Nathanael Garcia

This All-Star Cobalt chest protector does not offer additional bicep protection. The Diamond Pro, Adams XV HDX, or the Diamond iX3 comes with optional bicep padding. Champro chest protectors have bicep protection sold separately.
