FNDN™ Heated Thermal Waffle-Knit Shirt

Stay ahead of the cold with the FNDN™ Heated Thermal Waffle-Knit Shirt, a cutting-edge long-sleeve thermal that combines advanced heating technology with premium comfort. With heating elements on both the front and back, this shirt is crafted from an ultra-soft cotton blend in a weighted waffle-knit fabric, delivering moisture-wicking, lightweight, and breathable performance—ideal for any activity. Its versatile design, featuring a rib-knit collar and flatlock seams, makes it perfect to wear over a T-shirt, under a sweater, or as a standalone top, providing jacket-like warmth without the bulk.

Experience fully customizable warmth with FNDN™’s heat-on-demand technology. The soft-touch controls allow you to select from four radiant core heating levels: High, Medium, Low, and a battery-saving “Smart Pre-Heat” mode, which optimizes battery life by automatically adjusting from pre-heat to medium. The haptic button silently clicks when pressed, offering effortless tactile activation even when layered under other clothing.

Powered by a compact 10,000mAh USB battery pack, this shirt delivers 6-8 hours of continuous warmth. The rechargeable battery also doubles as a power source for your mobile devices, making it the ultimate cold-weather companion.
