FIRSTGEAR Heated Layer Shirt 12V - XL
SKU: F07O 527451
Description
Part #: 527451
Featuring high tech, moisture wicking stretch fabric with a close-to-skin fit, the Heat Layer Shirt from FIRSTGEAR (R) optimizes heat transfer, while reducing bulk. Seven heat panels on the chest, arms, neck, and entire back delivering more heat, in more places than any other garment. Each zone can be adjusted to fit the rider's body. The heat panels have soft, flexible alloy/silicon shaped for improved heat transfer. All this efficiency means less insulation and power is required to deliver and retain the desired heat. Put simply, it's the most versatile, high tech and efficient heated garment we have ever designed.
