Designed with versatility, function, and value in mind, Fieldsheer’s® Thermick Men’s Heated Baselayer and Women’s Heated Baselayer Shirt delivers uncompromising performance combined with our Mobile Heating 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 Thermick Heated Baselayer is an essential piece of any outdoor person’s 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 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 with the internal integrated touch control button.

The Thermick Heated Baselayer Shirt keeps you in the field and doing what you love longer. The thermal polyester blend offers numerous benefits, ensuring you’ll stay warm and dry all day long. Additionally, it’s an ideal fabric for layering as part of your outdoor equipment. Rib-knit cuffs make sure you stay warm without restricting mobility. 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. Multi-zone heating elements across your core deliver even warmth. The rib-knit cuffs keep it securely in place no matter what you’re doing from skiing, snowboarding, or any of your favorite winter activities. The Sweatsheer™ mesh liner wicks moisture away, keeping you dry, warm, and comfortable for hours on end, while the thermal midweight base layer delivers another level of protection.

The Thermick 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 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 Thermick Heated Baselayer Shirt lets you adapt and stay warm in any environment, from arid desert conditions to high Alpine timberlines. Men’s Thermick Heated Baselayer Shirts come in grey, and women’s are made in a stylish tan.
