We've learned the hard way. No matter what the weather report says, pack your Venture Heat liner. Cold does more than make your day no fun. Being uncomfortably cold causes fatigue, lowers your reaction time and increases the chance of injury. A 12V liner plugs into both Ducati and BMW rental bikes to make it the ultimate layer. From the chilling fog of the California coast to a sudden snow flurry in the Alps Venture Heat keeps our guides safe and in a much better mood. We like the reliable low draw heat and the clever control options. Learn about the various heated gear options venture heat offers at ventureheat.com.
