Men's Black Heated Baselayer Shirt, Bluetooth, 2X, 7.4V

The Mobile Warming Bluetooth-enabled Primer Plus heated baselayer shirt is designed for the outdoor enthusiast to keep your core warm. Its moisture-wicking, warmth, and stretch features make it a versatile baselayer in the winter, or a standalone shirt during outdoor activities. The Primer Plus is made from a four-way stretch anti-microbial 88% polyester and 12% spandex blend that provides a comfortable next-to-skin feel. Flat-lock seams, moisture-wicking mesh liner, and side-stretch panels conform to your body and allow for maximum body movement. The Primer Plus heated baselayer has integrated, concealed heating panels powered by sturdy yet light-weight 7.4-volt Far-Infrared Heating System. There are three heating elements, one on the back and two on the chest. The heating system can provide temperatures ranging from 135°F on high to 90°F on low. On high, expect 2.5 hours of heat, and on low for up to 10 hours. The Primer Plus has two ways to adjust the temperature. First, the built-in touch control button. With a simple button push, you can select from four heat settings. Second, Bluetooth control is available with the MW Connect™ app. Through the MW Connect™ app, you can adjust individual heat levels to your liking. MW Connect™ allows you to get real-time updates on battery levels and update your garments when new firmware becomes available. Includes the 7.4V (2200mAh) Lithium-Ion battery and a micro USB charging cable. You can expect up to 10 hours of heat per charge.
