The Mobile Warming Heated Base Layer Vest by Fieldsheer is a battery-powered heated vest designed to provide warmth without bulky layering. This innovative baselayer vest features multi-zone adjustable heat panels on the front and back (2 chest zones and 2 back zones) that radiate heat powered by a 7.4v Powersheer Mini rechargeable lithium-ion battery. The vest offers 4 selectable heat settings ranging from 90°F to 135°F, delivering up to 10+ hours of heat per charge depending on the setting (1.8+ hours on high, 7.2+ hours on low).

The vest is constructed with a 4-way stretch outer shell for flexibility and comfort, featuring a moisture-wicking mesh liner to keep you dry during activity. It includes an integrated waterproof touch control button with multi-colored LED indicator, allowing you to adjust heat settings without removing layers. You can also control temperature and monitor battery level through the MW Connect App via Bluetooth connectivity. Additional features include a YKK front zippered closure, dedicated battery pocket for secure storage, Odorsheer anti-odor technology, and USB-C charging input for convenient recharging.

Designed for versatile use from skiing and hunting to work and everyday activities, the vest is unisex and machine washable. Available in sizes SM through 3XL, it provides an efficient heating solution that eliminates the need for excessive layering while maintaining a sleek, low-profile design.
