What people say after their first cold week.
“I have Raynaud's and my fingers used to go white on the walk to the station. Not once since these arrived.”
Marisol Okafor-Reyes
Chicago, verified buyer
“Bought the pair for my dad for the football. He now takes one half to the allotment and I never see it again.”
Tom Whitcombe
Leeds, verified buyer
“Warmer than the ones I had before and the magnet thing is genuinely clever. Kept me warm through a delayed train.”

Questions, answered before you ask.
How long does a full charge take?
About three and a half hours from empty with the included USB-C cable and any phone charger. The indicator light turns off when both units are full.
Can I use just one half?
Yes. Each half has its own battery and heater. Snap them together to charge both at once and to carry them as a single unit.
Is it safe to hold against skin?
The top setting reaches about 126°F. It is fine to hold, but do not press it against bare skin for long stretches. Use the low setting for children and for anyone with reduced sensation.
Can I fly with it?
Yes, in carry-on luggage. The batteries are small and well under the 100 Wh limit airlines use for portable electronics. Keep them in your cabin bag, not checked luggage.
What if it does not keep me warm?
Send it back within 60 days for a full refund. We cover return shipping in the US.
