The three heat settings really do make a difference depending on what I'm doing outside.










Electric Heated Base Layer Set with 3-Mode Temperature Control for Cold Weather | Thomler
Early Black Friday Sale
Stay Warm All Day with Electric Heat Technology Built In
When the temperature drops and ordinary clothes aren't enough, this electric heated base layer set delivers warmth exactly where you need it. The set includes a long-sleeve crew-neck top and full-length pants, each with built-in heating elements powered by any standard USB port. Three adjustable heat settings let you dial in your comfort level whether you're on the slopes, working outdoors, or simply commuting on a freezing morning. The slim profile fits smoothly under your regular clothing without adding bulk, and flatlock seams prevent chafing even during all-day wear. Forget heavy, restrictive winter layers—this heated underwear system keeps your core warm so you can move freely and focus on what you're doing. Perfect for skiing and snowboarding, ice fishing, hunting in freezing conditions, cold-weather construction work, winter hiking, or anyone who spends extended time outdoors when it's truly cold. The rechargeable USB power supply means no disposable batteries and easy charging from any laptop, power bank, or wall adapter.
Why You Need This
- Built-In Heating Zones: Warmth targets your torso and legs where you lose heat fastest, so you stay comfortable even in subzero wind.
- Three Heat Settings: Low, medium, and high modes give you total control—adjust on the fly as conditions change or activity intensity shifts.
- USB Rechargeable: Plug into any USB port to power up; no need to hunt for specialty batteries or worry about running out mid-adventure.
- Flatlock Seam Construction: Smooth, chafe-free stitching sits flat against your skin for irritation-free comfort during long, active days.
- Slim Fit Design: Hugs your body without bunching, so you can layer a jacket, vest, or shell on top without feeling bulky or restricted.
- Zippered Hip Pocket on Pants: Secure your keys, phone, or small essentials while you're out in the cold.

What Our Customers Say
Discover what makes THOMLER special.
Finally found base layers that don't bunch up under my winter coat like crazy.
USB charging beats hunting for batteries in the cold every single time.
I wear these under my work clothes on construction sites and they keep my core warm without any restriction. The flatlock seams don't irritate my skin even after eight hours straight.
Grabbed a pair for ice fishing season and honestly wasn't sure they'd live up to the hype, but I've stayed comfortable in conditions where I'd normally be shivering by noon.
The zippered pocket on the pants is honestly clutch for keeping my phone accessible without digging through multiple layers. Sizing ran true to the chart, which I appreciated since I was ordering online.
