Designed with versatility and function in mind, Fieldsheer's Merino 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 thick enough to be worn on its own, the Merino Heated Baselayer is an essential piece of any outdoor person's kit. Our powerful Powersheer Standard 7.4-Volt Lithium-Ion Batter 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.

Part of our Performance Series, the Merino Heated Baselayer Shirt keeps you in the field and doing what you love longer. Merino wool offers numerous natural benefits, including anti-static properties, better insulation than cotton and synthetic fabrics, and is naturally breathable, ensuring you'll stay warm and dry all day long. Additionally, it's an ideal fabric for layering as part of your outdoor equipment. The contoured hoodie provides an added layer of protection from the elements, while in-seam cuffed thumbholes make sure your hands stay warm without restricting mobility. Waist and chest pockets provide extra storage, while the integrated touch control button makes operation easy and instant. Perfect as your first layer for the coldest winter days in backcountry powder, but thick enough to be worn on its own during a late fall camping trip or early spring morning jog. 2 large multi-zone heating elements in the back of the shirt keep your core temperature warm and regulated in even the harshest winter conditions.

The Merino 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's Performance Series delivers unparalleled performance and rugged durability without sacrificing comfort or mobility. Since 1978 Fieldsheer has been a leading manufacturer of outdoor apparel, men's heated clothing, and women's heated clothing. We know that conditions can change rapidly, and our Merino Heated Baselayer Shirt lets you adapt and stay warm in any environment, from arid desert conditions to high Alpine timberlines.
