Stay active and stay warm with the CW-X Insulator Web top. Just because there's a whole lot of winter and cold outside doesn't mean you've got to be stuck indoors all season long. Featuring Auto-Sensor nanotechnology, it's as if this top had a built-in computer to automatically adjust the thermostat up or down as you need it. Not only that, but it also wicks away moisture like none other, keeping you warm and dry on your excursions. Silver dioxide fibers keep the fabric smelling fresh and Support Web kinesiology-taping technology creates a support system for muscles of your upper back to help your balance, posture, and arm motion. There's more technology going on in this top than in a TI-83.
