Mobile Warming Primer Heated Shirt 7.4 Volt Mens Black XL

The Mobile Warming® Bluetooth®-enabled primer heated base layer shirt is designed for the outdoor enthusiast. From skiing, hunting, hiking to running or just working outdoors, the primer shirt complements your outerwear to keep a warm core. Its moisture-wicking, warmth, and stretch features make it a versatile base layer in the winter, or a standalone shirt during outdoor activities in the spring and fall. The primer is made from a four-way stretch anti-microbial polyester-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 heated base layer has integrated, concealed heating panels powered by sturdy yet light-weight 7.4 Volt far-infrared heating system. The 7.4 Volt system has three heating elements, one on the back and two on the chest, that add heat to critical areas that keep your core warm. The primer’s 7.4 Volt 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, the primer can provide heat for up to 10 hours! The primer 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, we’ve incorporated Bluetooth® control with our MW Connect™ App. Through the MW Connect™ App, you can quickly toggle through all connected Mobile Warming® devices and 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. All day, any weather. The primer heated base layer shirt is a versatile insulating layer that keeps you warm all winter long.
