FEATURED REVIEW   “I love my Jacket from Volt. It puts the perfect amount of heat on my neck and upper back. I love the fit and feel of the fabric and I really like the look. Well done Volt, thanks for keeping me warm.” - Kamila, CA - The Volt Heated Thermal Half Zip (THZ) is an extremely versatile mid weight jacket.  The Thermal Half Zip is powered by the included VB550 5000mah 5 volt rechargeable battery that includes a USB output, micro usb input and type C fast charging input.  This athletic but stylish pullover jacket can be worn as a mid layer or outer layer depending on the outside temperature and/or your desired core temperature. The THZ features a two zone heating system that targets the back of the neck through the collar and the upper back between your shoulder blades.  The patented Zero Layer® Heat System provides optimal heat transfer, helping the heat to penetrate deep in to your body’s core for a superior warming experience.  By using a 3 level external silicone switch the user will be able to easily change heat settings and visually confirm which setting the jacket is on.  As with all of the Voltheat.com products, the lower the heat setting you are on, the longer the battery will last.  The Volt Heated Thermal Half Zip is made of a brushed fleece that helps your body stay warm and dry.  The antimicrobial fabric will help keep the garment fresh and cut down on the frequency of washing.  The Volt Heated Thermal Half Zip is machine washable once the lead wire is protected with the attached rubber cap. 88% Micro-Poly shell fabric, 12% spandex Jersey with brushed fleece lining Antimicrobial treated fabric Contrasting top stitching accents Tricot brushed fleece stand up collar Includes 5V VB550 rechargeable 5000mah battery and charging cable Battery includes a Type C input for fast charging (Type C charging cable not included) Machine Washable Zero Layer® Heat System provides unmatched heat output: High 2+ hours, Med 4+ hours, Low 7+ hours Zero Layer® heat system eliminates bulk while providing more efficient heat transfer.
