Maybe one day humans will evolve body armor, but until then it's a good call to wear the Alpinestars Evolution Jacket when you're pushing it to the limit. Crashes come in all shapes, sizes, and intensities, but the Evolution is equipped to handle all of them, with strategic and removable padding that sucks up impacts so your body doesn't have to. The stretchy, breathable mesh body of the Evolution incorporates a removable and replaceable CE certified ergonomic back protector, along with slim removable shoulder protectors and soft chest and side padding. If you pull out the back protector, you can slide a hydration reservoir into the sleeve, and also make use of the front and rear hose routing ports to grab a quick and easy drink. There are also two pockets on the kidneys, for easy access to key gear, and a low profile front zipper that allows for extra ventilation and fit customization. Alpinestars also designed the Evolution to be compatible with the Bionic Neck Support BNS system, and designed the snug fitting sleeves to work easily with elbow pads for full protection.
