No Chill The return of the pumpkin spice latte doesnt even begin to make up for the inevitable drop in temps that can mean the end of the riding season in many parts of the world - lets turn up the heat and keep it on two wheels when the warm weather heads south. The bodys natural cold-weather defense is to draw warmth to vital organs at the expense of your hands and feet. Combat that discomfort by warming up your torso and arms, keeping your other extremities toasty. Hot Tech With the integrated Bluetooth controller, you can easily manage your warmth settings. It provides 10 levels of temperature control, and you can fine-tune your preferences through the free iOS or Android app. Alternatively, you can use the built-in soft touch controller with 3 levels of temperature control.
