Heated Thermal Underwear Set USB Powered with 3 Heat Settings for Skiing Hiking and Outdoor Sports

Warmth You Control When the Cold Sets In

This heated thermal underwear set pairs a long-sleeve top with matching pants, both fitted with built-in heating elements you power over USB. Choose from three heat settings to decide how much extra warmth you need, while the heating zones on your body and legs put that warmth exactly where the cold bites first. The slim, stretchy fit sits comfortably under your everyday clothes, so whether you are on the slopes, working outside for hours or out on a winter walk, you stay comfortably warm without the bulk.

Benefits of This Heated Thermal Underwear

• Targeted heating zones: warmth is placed on your body and knees, where you feel the cold most.
• Three heat settings: switch between low, medium and high to match the weather and your activity.
• USB powered: plug into a USB power bank and go, with no disposable batteries to replace.
• Flat seams: no rubbing or chafing, even on long days in the cold.
• Close but flexible fit: layers neatly under jackets, ski wear or daily outfits without adding bulk.
• Zip hip pocket: keeps the power bank or small essentials secure while you move.

Designed for Cold Days and Winter Adventures

Think of this set as a warm second skin for freezing temperatures. The elastic waistband and crew neck give a comfortable, secure fit, and the flexible cut lets you move freely, perfect for skiing and snowboarding but just as useful for standing work in the cold or a daily walk through a winter landscape. For anyone who regularly faces cold mornings and long hours outdoors, this heated base layer turns winter into something you can simply enjoy.
