Protection: 4-point CE armour, pocket for back & chest
Comfort: Stretch panels, Vented zips
Extras: Detachable thermal liner

All the protection you want, wrapped into a pure brown jacket! This jacket is an absolute corker! The full brown style is not something that Alpinestars often produces, but it gives the jacket an awesome look. This jacket features external sliders with shoulder and elbow armour, but you've also got the option to insert a back and chest protector. Once you try this jacket on you won't want to take it off: It's comfortable, understated and would look awesome paired with motorcycle jeans.
