★★★★★

Game changer for skiing

I've tried every thermal layer going and nothing comes close to this. Wore the full set under my ski suit for a week in the Alps, stayed warm on every chairlift and never overheated on the runs. Worth every penny.

Finally back to running in winter

I stopped running outside in winter a few years ago, just couldn't handle the cold. Got the heated top and it's completely changed things. Warm from the first minute, light enough that I barely notice it. Brilliant.

Frequently Asked Questions

Everything you need to know about our Heated Base Layers.

How do ToastyBody heated base layers work?
USB-powered heating elements built into the fabric.
Our heated base layers use ultra-thin heating elements built into the fabric that warm up when connected to a USB power bank. The top has 16 elements covering your stomach, back, and elbows; the pants have 12 elements across your hips, thighs, and calves. A single chest button lets you cycle through three heat settings so you stay comfortable no matter the conditions.
What's the difference between the top, the pants, and the set?
Coverage, element count, and price.
The Heated Base Layer Top ($119.99) has 16 heating elements warming your stomach, back, and elbows. The Heated Base Layer Pants ($119.99) have 12 elements across your hips, thighs, and calves. The Heated Base Layer Set ($199.99) gives you both, 28 elements in total and is the best value if you want full-body warmth from head to toe.
How long does the heat last?
Depends on the heat setting and your power bank capacity.
Runtime depends on your power bank capacity and which heat setting you use. A larger power bank (10,000 mAh) on the low setting can provide several hours of continuous warmth. Switching to medium or high will reduce runtime but deliver more intense heat. We recommend carrying a higher-capacity power bank for full-day activities like skiing or hiking.
How fast do they heat up?
Within 30 seconds.
You'll feel the warmth within 30 seconds of switching on. The heating elements distribute heat evenly across the covered zones. No hot spots, no cold patches, so you warm up fast and stay comfortable for as long as you need.
Can I control the temperature?
Yes, three heat settings at the press of a button.
Yes. Each garment has three heat settings; low, medium, and high, controlled by a single button. Press to cycle between them depending on how cold it is and how active you are. Heading into the elements? Turn it up. Starting to warm up mid-run? Drop it down.
What power bank do I need?
Any standard 5V/3A USB power bank.
Any standard 5V/2.4A USB power bank will work. Power banks are sold separately, we recommend a 10,000 mAh capacity or higher for the best runtime. If you're buying the set, you'll need a power bank for each garment as they each have their own connection.
Can I wash them?
Yes, just disconnect the power bank first.
Yes. Disconnect and remove the power bank, then wash on a cold, gentle cycle inside a laundry bag. Always air dry, avoid tumble dryers, bleach, and dry cleaning. Refer to the care label inside your garment for the most accurate instructions.
Can I wear them under my normal clothes?
Yes, they're designed to be worn as a base layer.
Absolutely, that's exactly what they're made for. The slim, form-fitting design sits close to the skin and layers comfortably under ski gear, workwear, or everyday clothing without adding bulk or restricting movement.
What activities are they suitable for?
Any cold-weather outdoor activity.
Our heated base layers are built for skiing, snowboarding, hiking, jogging, motorcycling, snow clearing, and any other activity where staying warm is the difference between enjoying yourself and cutting it short. The flexible, close-fitting design moves with you so they never get in the way.
What sizes are available?
XS to 3XL in men's and women's fits.
All three products are available in men's and women's fits, sized XS through 3XL. Because these are close-fitting base layers, we recommend checking the sizing chart on the individual product page before ordering.
Are ToastyBody heated base layers safe to use?
Yes, low-voltage and designed with safety in mind.
Yes. Our heated base layers run on low-voltage USB power (5V) and are built with safety circuits to prevent overheating. As long as you follow the care and usage instructions, they're safe for everyday wear.
Do I need one power bank for the top and one for the pants?
Yes, each garment has its own connection.
Yes, the top and pants each have their own USB connection, so you'll need a power bank for each when wearing them together. If you're buying the set, we recommend picking up two power banks so you can run both garments simultaneously for full-body warmth.
