Good protection
These fit with compatible aplinestar jackets and give added protection on your chest in case of a crash. They did not make the jacket uncomfortable for me which was nice.

Product excellent - return system faulty
I returned this product and have a return completion receipt and record from Amazon and now I’m getting a message I have to return the product or they will take back my refund. How do I return something I already returned and have a receipt for returning???

REVOLUTIONARY! I believe this is the first CE2 divided chest protector!
Thinner, Lighter, and more Flexible than my old CE1 Protectors!. This is a crazy leap forward in materials engineering. Good job Alpinestars!
