Alpinestars Caliber Jacket BROWN 3107319-80 ALL SIZES


Alpinestars Caliber Jacket 

The Alpinestars Caliber Jacket is an anomaly that is both subdued and boisterous. SoCal Alpinestars sport bike styling executed in a muted tone creates a jacket that looks at home on an Italian sport bike or classic cafe racer. Premium leather with accordion leather stretch inserts provide both abrasion resistance and freedom of movement. Stretch panels on the sleeves and chest keep the jacket snug without feeling constrained. Embossed logos and direct print graphic details are apparent, but not overly loud. CE rated armor at the elbows and shoulders protect against impacts. Slip in back and chest armor inserts (sold separately) to complete the impact protection. The overall outcome of the Alpinestars Caliber Jacket is sporty styling that hides it technical prowess.
