Outdoor workers and cold-weather enthusiasts, these Gerbing heated pants will completely change how you handle winter! Powered by a 7V 2700mAh rechargeable battery, these base layer pants feature strategic Microwire heating panels placed on the knees, thighs, and backside where you need warmth most. The three heat settings give you control: High (135°F) for about 2 hours, Medium (115°F) for 4 hours, or Low (105°F) for up to 8 hours of continuous warmth. The 92% polyester/8% spandex fabric provides comfortable stretch that moves with you during activities like hunting, skiing, working outdoors, or even just watching games in cold stadiums. The touch-button control makes adjusting temperature intuitive, and the entire system is machine washable (gentle cycle) for easy care. Unlike bulky layers that restrict movement, these heated pants provide targeted warmth without adding bulk, making them perfect under your regular winter pants. The included battery and charger mean you're ready to go right out of the box. Whether you're facing freezing temperatures at work, enjoying winter sports, or just someone who's always cold, these heated pants deliver comfortable, consistent warmth that outer layers alone can't match. Gerbing's lifetime warranty shows they stand behind their quality - this is serious cold-weather gear designed to perform when you need it most.
