Designed with versatility, function, and value in mind, Fieldsheer’s® Proton women’s Heated Baselayer Pants deliver uncompromising performance combined with our Mobile Warming® Technology.  Thin enough to be worn under jeans, snow or ski pants, or other outdoor 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 Pants feature multi-zone heat elements that deliver even warmth without sacrificing mobility. A midweight baselayer, the Proton is ideal 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 Pants allow 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. Don’t let cold conditions or inclement weather keep you from enjoying your favorite winter activities with Proton Heated Baselayer Pants.
