Verified Customer Reviews for Alpinestars Proton Waterproof Textile Jacket
Great jacket, great company
31 July 2025 by Simon
The jacket is comfortable and very functional, it has great vents which cool things down as I only ride in warm/ hot weather.
Wish it came with the back protector as that was an extra sixty quid.
Must say Sportsbikeshop are the best company I ve ever dealt with for anything, everything they do is perfect and an example to many other companies!!

Description
The Proton is a street sport jacket offering an innovative modern style with premium comfort. With a main chassis constructed from 35% sport leather and 65% stretch textile for the optimal blend of abrasion resistance, light weight, and comfort. With a 2L waterproof membrane construction, direct ventilation panels and a detachable thermal liner, the jacket can be easily adapted to the weather.
The Proton Waterproof Jacket has a new inner construction that is great for adding protection inserts via upgrades with easy access pockets for both back protectors and chest protector inserts. It also comes equipped with the double pocket which fits both a regular and a long back protector, for riders interested in riding with more protection. Featuring an engineered fit designed to deliver the highest level of active upper body protection, the jacket is Tech-Air® Ready and can accommodate the Tech-Air® 5 or Tech-Air® 3 Airbag System. Strategically positioned stretch panel inserts have been designed to accommodate a Tech-Air® Airbag System, allowing for expansion when the airbag inflates and offering a high level of anatomical performance and a superior fit when riding without the system fitted.
