Great chest protector. It feels robust from the thick padding to the plating without being bulky. This CP provides the best side protection I’ve seen with a slight wrap around due to the plating breaks. I love that it can be cleaned.

This protector is all flash and no substance! I've already lost a screw and they don't have replacements. It's been over a year so I can't return it. Overpriced. Get the West Vest instead for better protection and a product that will last!

High school game. Took one last night straight back just below the mask throat protector. POW! Easily 85-90 mph off the bat, dead center body mass. It was loud. Decent size crowd gasped and then went "Ooooh". Everyone froze. Ball went half way back to the pitcher. Catcher grabs it and runs to the pitcher saying, "You ok André", I smiled. Both teams coaches come towards me as does my partner out the B. I FELT NOTHING. They looked puzzled and expected injury. Game changer did its job. All-Star Cobalt is the best chest protector on the market. Very comfortable and it is customizable to your needs and body.

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 ProAdams XV HDX, or the Diamond iX3 comes with optional bicep padding. Champro chest protectors have bicep protection sold separately.
