Fieldsheer’s® women’s Proton Heated Baselayer Pants are an all-season favorite designed to be worn under jeans, ski or snowboard pants, or other outdoor gear. A sporty silhouette allows them to be worn on their own as stylish activewear. Powered by Powersheer™, the 7.4-Volt Lithium-Ion battery holds up to ten hours of power per charge delivering comfort no matter what nature throws at you and with a universal USB charging port. The subtle camouflage design adds a level of detail and sophistication to the front and back, while a 3/4 zip keeps the Proton Heated Baselayer Shirt securely in place. Integrated with our Mobile Warming® Technology, simply activate one of four heat settings with our proprietary Bluetooth® integrated MW Connect™ app. The Sweatsheer® liner draws moisture away from the body, providing lasting comfort without sacrificing mobility. 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.
