Fieldsheer Mobile Warming 7.4V Womens Proton Baselayer Heated Shirt

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.

Perfect for every season, the Proton Heated Baselayer Shirt features a subtle gray camouflage detail across the front and back, giving it a sporty vibe. At the same time, a 3/4 zipper allows you to easily layer up or down as the conditions change. Multi-zone heat elements across the back deliver even warmth, and in-seam thumbholes keep your hands warm without sacrificing mobility. A midweight baselayer, the Proton is perfect for days when you begin early in cold conditions, and our Sweatsheer technology quickly wicks moisture away from the body, keeping you warm and dry for hours on end. The Proton Heated Baselayer Shirt allows you to keep going no matter what the conditions throw at you, and by maintaining a healthy temperature, you reduce fatigue, muscle soreness and decrease sensitivity.

Fieldsheer continues to deliver unparalleled performance and rugged durability without sacrificing comfort, mobility, or value. Since 1978 Fieldsheer has been a leading manufacturer of outdoor apparel and heated clothing. We know that conditions can change rapidly, and our Proton Heated Baselayer Shirts let you adapt and stay warm in any environment, from early spring jogs to late fall camping or a fresh powder day in the backcountry. Versatility is the name of the game when it comes to cold conditions, and our team of designers and engineers strive to produce cold-weather gear that won’t let you down when you need it most. The poly-blend combined with a thermal midweight layer and rib-knit cuffs and waist offers unparalleled comfort and performance, keeping you in the field and doing what you love longer.
