FNDN™ Heated Skin-Fit Base Layer PRO

Engineered for maximum performance in extreme conditions, the FNDN™ Heated Skin-Fit Base Layer PRO delivers all-day comfort with advanced heating technology in a slim, versatile design. Built from lightweight, breathable, moisture-wicking stretch fabric, this long-sleeve base layer with heated thumb-hole cuffs provides the warmth of a parka without the bulk - perfect under any jacket or worn on its own.

The PRO model sets itself apart with added chest heating zones, the ability to run up to four BEGO batteries at once, and higher-capacity cells for extended runtime. With soft-touch controls, you can adjust through four Radiant Core heating levels—High, Medium, Low, and Smart Pre-Heat—across your chest, back, and hands. Designed without a hood for easier layering, the PRO base layer is the ultimate upgrade for work, play, or training outdoors in freezing temperatures.

**Does not connect to the base layer pant (via cable) like the original base layer top, this is designed to work separately. **
