Frequently Asked Questions

Everything you need to know about our Heated Base Layers.

What are heated base layers?
Thermal wear with built-in heating zones.
Heated base layers are thermal tops and pants with integrated heating panels, designed to provide consistent, customisable warmth underneath your regular winter clothing.
How do they work?
USB-powered heat at the press of a button.
Each piece has discreet heating elements that connect to a USB power bank (sold separately). With one-touch control, you can cycle between 3 temperature levels.
Are heated base layers safe?
Yes, low voltage, CE certified, and skin-safe.
ToastyBody base layers use low-voltage heating and are thoroughly tested for safety. They're safe for direct skin contact and include built-in temperature regulation.
Do I need one or two power banks?
One for the top, one for the pants.
Each garment has its own USB lead. To heat both pieces at once, you’ll need two power banks. We recommend our twin pack at checkout for best performance and value.
How long does the heat last?
Up to 10 hours depending on settings and battery size.
With a 10,000 mAh power bank, expect 3–4 hours on high, 6–7 on medium, and up to 10 hours on the low setting. Runtime varies by ambient temperature and battery quality.
Can I wash the base layers?
Yes, machine washable once the batteries are removed.
Always unplug and remove power banks before washing. Use a laundry bag, gentle cycle, and air dry only. Avoid bleach or tumble drying.
Can I wear them under regular clothes?
Absolutely, designed for layering.
Heated base layers are slim-fitting and flexible, made to sit comfortably under jackets, hoodies, or workwear. No bulky wires or awkward bumps.
Where do the batteries go?
Discreet pockets in the hem and waistband.
The top has an interior hem pocket, and the pants have a slim waist pocket—both designed to keep your power banks secure and out of sight while in use.
Are they suitable for skiing, hiking, or work?
Yes, built for performance and durability.
Perfect for outdoor sports, working outside, commuting, or simply staying warm. Lightweight yet tough, with stretch fabric that moves with you.
Do they come in men’s and women’s sizes?
Unisex design with flexible sizing.
Yes, the fit is unisex and available in a full size range. Be sure to check our size guide to get the best fit for your body type and layering needs.
Can I return them if they don’t fit?
