Caliber V2 Leather Jacket

What protection does the Caliber V2 Leather Jacket provide?

The Caliber V2 Leather Jacket is an AA-rated protective motorcycle jacket built for aggressive street and sport riding. It includes Nucleon PLASMA Level 2 elbow protectors, Nucleon Flex Pro Level 2 shoulder protectors, and low-profile DFS ST shoulder armor for impact protection in key zones.

Its main chassis uses 0.8-0.9 mm full-grain bovine leather, combining abrasion resistance with a softer, more mobile feel than heavier race-focused leather jackets.

Is the Caliber V2 Leather Jacket waterproof?

No, the Caliber V2 Leather Jacket is not described as a waterproof motorcycle jacket. It is a leather sport jacket designed for all-season use through its removable thermal liner rather than a fixed waterproof membrane or laminated rain construction.

It does include internal waterproof storage compartments for small essentials, but the jacket itself is best suited to dry conditions or changing temperatures rather than regular wet-weather riding.

Is the Caliber V2 Leather Jacket compatible with Tech-Air® airbag systems?

Yes, the Caliber V2 Leather Jacket is Tech-Air® Ready. It is compatible with the Tech-Air® 7X System, Tech-Air® 5 Plasma System, Tech-Air® 5 System, and Tech-Air® 3 V2 System.

This makes the jacket a strong option for sport riders who want a leather chassis with low-profile built-in armor and the option to add Alpinestars electronic airbag protection. You can also check the Tech-Air® compatibility checker for system details.

How does the Caliber V2 Leather Jacket fit, and how should I choose my size?

The Caliber V2 Leather Jacket has a sport fit with a streamlined silhouette, but it is designed to feel lighter and less restrictive than a full race jacket. Accordion leather panels at the shoulder blades and waist, leather stretch inserts on the sleeves and chest, and HRSF armpit panels help it move more naturally in the riding position.

For the best fit, use the Alpinestars size guide and base your choice on chest and waist measurements. If you plan to use a compatible Tech-Air® system or colder-weather layers, account for that before selecting your size.
