Frequently Asked Questions
Not a thing. The wire and connections are insulated with plastic.
Electrical systems today are designed for accessory use. Check your manual or with the dealer to find your systems peak output in watts. Take away the watts draw of the system itself. The remainder can be used to run electrical accessories.
Black Jack products do not require external temperature control. Our "balanced heat" system provides the optimal wire - resistance/length for each size of product. This produces a just right, comfortable amount of heat. The simple on/off switch we built in is all that's required so you can always "Ride Warm With Black Jack"....
Hand wash, gently in cool water with a low-suds detergent and hang to dry.
Each Black Jack garment comes with a Battery Harness put together to safely handle any two of our heated garments (through the use of an available splitter).
Watts=ampsxvolts. Wattage listings are a reference to indicate load to your system. A given product size requires a unique combination of heating wire. Wire distribution/length determines the resistance. The volt output of your system determines the amps flowing to the product. Wattage listed by the manufacturer may be determined with a voltage different from yours and using a product of a different size or a size average. Either way the wattage given may not relate to the actual product warmth of the size you will get.
More important to the amount of warmth you will feel are proper fit, heater wire distribution and knowing how to get the most from your heated garment.
A healthy person is not harmed permanently by mild exposure but most bike riders know the uncomfortable feeling caused when it takes hold. The body to counter the cold penetrating its' core retains heat by restricting blood flow to the arms and legs. This causes impaired nerve function resulting in stiffness of movement and a slowing of reactions. That's why even very mild Hypothermia is not good news on a bike.
Heated Garment Benefits
The toasty warm feeling is great but as a safety issue the main benefit is guarding the body's trunk temperature against the penetration of cold, particularly over long periods of exposure.
Each product comes with a battery harness and instructions for hooking it up to a 12 volt system. The harness is long enough for almost all installations however harness extensions are available. Most systems have no trouble handling one or two garments. On how to determine what your system will handle check our "Electrical System" page.
Insulated garments trap body heat to keep you from feeling cold. Our thermal electric technology provides radiant heat within our liner to wrap you in a layer of warmth. The closer the radiant heat is to your body, the more warmth you will feel.
To maximize your comfort we suggest the following:
Take advantage of our form fit sizing, choose a liner that is snug but not tight for uniform contact and an all-over feeling of warmth. Try a T-shirt type, single layer of clothing under your heated liner. If that's proves too warm use something a bit heavier. You will soon learn the appropriate weight to use under various riding conditions.
When extra warmth is needed wear a weather proof, insulated jacket over your liner.
Garment Liner Care
A little care and consideration will extend the life of your warm friend. Avoid any action that will penetrate or damage the thermal-electric wiring inside the liner. Roll the liner to compact it for on-board storage. Gently hand wash and rinse in cool water - hang to dry.
