Fieldsheer Mobile Warming Women’s Proton Heated Baselayer Shirt with Rechargeable Battery Pack

Designed with versatility, function, and value in mind, Fieldsheer’s Proton women’s Heated Baselayer Shirt delivers uncompromising performance combined with our Mobile Warming Technology. Thin enough to be worn under an outer layer, snow jacket, or rain gear but stylish enough to be worn as activewear, the Proton Heated Baselayer is an essential piece of any woman’s outdoor kit. Our Powersheer 7.4-Volt Lithium-Ion battery is supported by a universal USB charging port and can provide heat for up to 10 hours on a single charge. 4 distinct heat settings put you in control, and with seamless Bluetooth connectivity on our proprietary MW Connect app, you can stay warm in even the harshest winter conditions. Easily toggle between heat settings to find the perfect level of comfort on even the coldest winter days.
