The Fieldsheer powered by Mobile Warming Technology Bluetooth®-enabled Primer heated men's 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 baselayer 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 baselayer has integrated, concealed heating panels powered by a sturdy yet light-weight 7.4-volt fine heating coil 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 57°C on high to 32°C 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 Fieldsheer® 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.
Please note: This garment runs small.
