Details

Slim heated thermal pants, built your way.

Take 3 heated zones for the waistband and knees, or step up to 8 zones that wrap your lower belly, your lower back and both knees. Wear them on their own around the house, or pull them on under roomier work, ski or snow pants.

  • Pick your heat: 3 zones or 8 zones. 3 zones ($89): a band across the front waistband and one zone on each knee. 8 zones ($99): two at the lower belly, two across the lower back, and one above and one below each knee.
  • Why go to 8? Heat on your back as well as your front, and knee heat that runs above and below the joint instead of one spot on the kneecap. For heat at the backs of the knees, the shins and the calves too, choose the 12-zone Varmth Heated Pants.
  • One button switches the heat on and off: on the right hip on the 3-zone pants, on the front waistband on the 8-zone pants.
  • USB powered. Runs on a standard 5V USB power bank, sold separately. Add a Cell 10K if you need one. On the 3-zone pants the USB lead sits in the zipped pocket beside the button.
  • Two fabrics. 3 zones: brushed cotton with a soft fleece lining, an elastic waist and a slim, tapered leg. 8 zones: a high-stretch, close-fitting tight with a gathered elastic waistband.
  • 3 zones: black or gray, women's US sizes XS to L. 8 zones: black, women's US XS to L. A close thermal fit. Wrong size sent? We send the right size free.

Questions

Does it come with a power bank?

No. It runs on a USB power bank, sold separately. Use one you have, or add one of our Cell power banks.

Is shipping free?

Yes, on US orders of $70 or more. Under $70, standard tracked shipping is $8, shown at checkout before you pay.

Where do orders ship from?

Some items ship from our US warehouse, others from our international warehouse, so a mixed order can arrive in more than one parcel, each with its own tracking. The shipping page lists each product.

What's your return policy?

Start a return within 7 days of delivery. It needs to be unworn and unwashed, with everything it came with; return postage is yours, and we refund the item price once it arrives. Damaged, faulty or not what you ordered? Tell us within 14 days and we put it right at no cost to you. On sized items, if we sent the wrong size, we send the right size free. Power banks, pocket warmers and the rechargeable insoles come back only unused: contact us first and we'll send the packing steps.

What does the warranty cover?

Every heated product and power bank we sell has a 14-day limited warranty against defects, counted from delivery. If it's faulty, we replace it or refund you, at no cost to you.

Can I fly with it?

Yes. Heated clothing and accessories that run from a separate power bank can go in a carry-on or a checked bag (TSA); take the power bank out first and keep it in your carry-on. Power banks, and anything with a built-in battery (pocket warmers, the Remote Control and App Control insoles), go in your carry-on only.

Who shouldn't use heated clothing?

Young children, and anyone who can't feel heat well or can't take the garment off on their own. Don't sleep in heated clothing. Stop if anything feels too hot.

Can I wear it against my skin?

Yes. It's a base layer, made to be worn next to your skin under your clothes. Start on low and check how your skin feels until you know it, and stop if anything feels too hot. Don't sleep in it.
