Alpinestars Core Jacket: Track-Ready Protection Meets All-Day Comfort

Engineered for sport riders who demand uncompromised safety without sacrificing mobility, this premium motorcycle jacket blends race-derived tech with street-smart versatility. Ideal for canyon carving, track days, or daily commutes in warmer climates—wherever performance matters most.

Why Riders Choose This Jacket:
– Elite Abrasion Defense: Full-grain 1.1mm leather construction withstands slides while molding to your body over time—no stiff break-in period needed.
– Modular Safety Ecosystem: Removable CE shoulder/elbow armor pairs seamlessly with optional Nucleon Level 2 back/chest protectors (sold separately) via snap-fit panels—perfect for upgrading protection before track sessions.
– Breathe Easy, Ride Hard: Laser-cut perforations across arms/torso + aerodynamic MotoGP-style back hump channel airflow during aggressive riding or summer highway miles.
– Freedom of Movement: Stretch poly-textile inserts at elbows/back move with you during lean angles—no restrictive tugging mid-corner—while underarm/waist flex panels accommodate varied riding positions (sportbike cruisers included).
– All-Day Wear Comfort: Soft 3D-mesh collar prevents chafing; zip-adjustable cuffs + Velcro® waist D-rings dial in your fit over base layers or casual wear off-bike.

Smart Integration Features:
Connect directly to Alpinestars pants via 360° waist zipper for full-suit stability at speed. Extended lumbar coverage shields your lower back during long rides while reflective accents boost visibility when dusk hits city streets—essential for commuters navigating traffic after work hours.

Upgrade Tip: Pair with Nucleon armor (sold separately) for FIM-certified impact defense during high-speed track weekends—the same tech trusted by MotoGP champions.

YKK® zippers ensure decade-long reliability while PE foam padding cushions spine/coccyx impacts without bulk—proving premium protection doesn’t mean sacrificing comfort mile after mile.
