    About Gerbing 12V Motorcycle Heated Jackets & Vests

    Gerbing 12V jacket and vest liners wire straight into your motorcycle's electrical system, so the heat lasts exactly as long as the ride — no battery to charge, no runtime to watch. Micro-alloy heating elements spread even, adjustable warmth across the core, back, and arms, layering cleanly under your existing riding jacket. Connect to a Gerbing temperature controller to fine-tune heat right from the handlebars. Pair with 12V heated gloves, pants, and all 12V motorcycle gear to build a full head-to-toe system.

    How 12V Motorcycle Heat Works

    Unlike battery gear, a 12V liner draws constant power from your bike through a fused battery harness, so warmth never fades on a long ride. The micro-alloy elements heat the chest, back, and sleeves, and a Gerbing controller lets you dial the temperature up in deep cold or down as conditions ease — all without taking your hands off the bars for long.

    Jacket Liner or Vest Liner

    Choose a full jacket liner for arm-to-core coverage on the coldest rides, or a vest liner when you want core warmth with less bulk under your gear. Both layer invisibly beneath your riding jacket and share the same 12V connection system.

    Built to Ride

    Gerbing pioneered heated riding gear and still builds it for real-world miles. Every 12V liner is backed by Gerbing's warranty for season-after-season reliability.

    Frequently Asked Questions

    Will a Gerbing 12V jacket liner drain my motorcycle battery?
    No. Gerbing 12V liners are designed to run off your motorcycle's charging system while the engine is running, drawing well within the output of most street bikes. We recommend connecting through the included fused battery harness and running heated gear with the engine on, not off a parked battery.
    Do I need a temperature controller for a 12V heated jacket liner?
    A controller isn't strictly required, but it's strongly recommended. Without one, the liner runs at full heat whenever it's connected. A Gerbing single- or dual-zone temperature controller lets you adjust the warmth as conditions change and run multiple heated garments at once, which is why most riders add one to their setup.
    Can I wear a 12V Gerbing liner off the bike?
    The 12V liners are built to connect to your motorcycle, so they aren't meant to run off the bike on their own. If you want heated gear you can wear walking around, at a campsite, or in the truck, choose Gerbing's 7V battery-powered line instead, which runs on a portable rechargeable battery.
    How do I size a 12V jacket or vest liner?
    Liners are meant to fit snugly as a layer, close to the body so the heating elements sit against you, with room for a base layer underneath but not bulky mid-layers. If you're between sizes, order your normal jacket size for a closer heated-layer fit. Check the size chart on each product page for exact chest and sleeve measurements.
    Can I connect heated gloves and pants to the same 12V system?
    Yes. The Gerbing 12V system is built to power multiple garments at once. Use a Y-harness to split power between your jacket liner, gloves, and pant liner, and a dual-zone controller to manage them. This lets you build a full head-to-toe heated setup that all runs off your motorcycle.
    Is the wiring hard to install on my motorcycle?
    Setup is straightforward. The fused battery harness connects directly to your motorcycle's battery terminals once, then a connector routes out to your gear so you can plug in and unplug each ride. No permanent modifications to the bike are needed, and the harness stays in place for the season.
