In this issue's Street Survival, we cover the essentials for staying warm on cold-weather rides. However, sometimes multiple layers of clothing simply won't do the job. What then? Electricity. That's right, 12-volt, DC-powered heated clothing plugged right in to your motorcycle's electrical system. In most cases, it's as easy as accessing your bike's battery terminals to get connected. With a variable power controller-necessary with any heated clothing-these garments keep you warm and toasty on the coldest of days and nights. Most of the manufacturers listed make a variety of heated products. Though there isn't a standard connector, many companies sell adapters that allow for mixing and matching of brands of clothing and power controllers.
Heated Jacket Liner - Gerbing's...
Heated Jacket Liner - Gerbing's Cascade Heated Jacket $425If you're particularly prone to being cold, you might consider heated jacket liners. They fit looser and therefore don't provide as much core body heat as a heated vest, but they more than make up for it with warmth to the arms. Liners also utilize strategically placed wires and light insulation, but Gerbing's Cascade Heated Jacket goes further-the three-quarter-length riding jacket is made from heavy-duty, waterproof Cordura and ballistics cloth with CE-approved armor in the elbows and shoulders. Special ports on the sleeves allow you to attach heated gloves to a removable, heated liner within. Multiple zippered vents increase the jacket's versatility.

Heated Vest - Widder System...
Heated Vest - Widder System 2 Lectric-vest $137The key to avoiding hypothermia is in maintaining core body temperature. That's why a vest alone, keeping your torso toasty, will help keep the blood flowing to the extremities, too. Heated vests are designed to fit snugly to get the warmth directly to your body. The vest utilizes strategically placed wire to provide the best distribution of heat. The Widder System 2 Lectric-vest uses a light Thinsulate insulation to hold in heat and reduce overall bulk. It also features a heated, fold-down collar and can be augmented with Widder's Lectric-ArmChaps.

Heated Pants - Tour Master...
Heated Pants - Tour Master Synergy Electric Heated Pants $140In really frigid stuff, a heated vest or jacket liner might not be enough. Heated pants are just the extra piece of the warmth equation for you. As in a vest, wiring is placed to maximize warmth; since it's your front side that's meeting the wind, the pants are like backward chaps, with the heat reaching the front of your legs and hips. Synergy Electric Heated Pants are unique in that the heating elements consist of lightweight, flexible, carbon-fiber strands instead of wire.

Heated Gloves - Tour Master...
Heated Gloves - Tour Master Synergy Electric Heated Gloves $140On a cold day, it's usually your fingers and hands that feel the chill first. When your hands get cold, you begin to lose dexterity and feeling, essential to operating the bike's controls. Unlike heated grips, heated gloves get the warmth directly to your digits. Just make sure the heated gloves you choose have a heating element going to each finger. These Synergy Electric Heated Gloves have a goatskin outer for abrasion resistance, plus a waterproof and breathable barrier for weather protection.
