Why We Like The Bionic Pro Chest Protector

The Alpinestars Bionic Pro Chest Protector feels softer and more flexible than most body guards for mountain biking, and we like wearing it on downhill rides about as much as we like wearing helmets, which is a lot. It offers the same level of protection as hard shells, while soft 3D mesh and abrasion-resistant textiles amplify breathability and mobility. The back protector is a CE-certified (EN14021) stone shield that we can remove for BNS compatibility.
