The Fieldsheer Bluetooth-enabled Ion heated baselayer pant is designed for the outdoor enthusiast. From skiing, hiking to running or just enjoying the outdoors, the Ion pants complements your outerwear. The Ion pant is made from a 4-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 Ion heated baselayer has integrated, concealed heating panels powered by sturdy yet light-w8 7.4-volt Mobile Warming Heating System. The 7.4-volt system has 3 heating elements, one on lower back and 2 on the thighs, that add heat to critical areas that keep your legs warm. The Ion'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 Ion can provide heat for up to 10 hours! The Ion pant has 2 ways to adjust the temperature. First, the built-in touch control button. With a simple button push, you can select from 4 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 Ion's technical performance and heating capabilities make it ideal for when you're getting active in the winter months.
