In their words
Cold doesn’t just hurt. It takes your hands off the job.
Real posts from people describing their cold hands. Their words, not ours.

“Indoors my hands are always freezing in the fall / winter / spring months.”
— MetaFilter
“I have trouble playing games, let alone FPS games, when my hands are cold because they also become stiffer.”

Gloves only keep in the heat you already have. Cold fingers have almost none to keep. Nothing you’ve tried added heat in your hand while it kept working.
How it works
Gloves hold heat. This one makes it.

Two magnetic halves
One for each hand
Rechargeable
Charge it like a phone
01
Press the button
A small rechargeable battery, like the one in your phone, sends power to a thin plate inside.
02
The plate warms up
It heats the way the wire in a toaster does, only far more gently.
03
The heat moves into your hand
Hold it while you think, then get back to the keys. When it runs low, charge it like a phone.

At your desk
Hold it between bursts of typing. Don’t wear it.
No fingerless gloves, nothing on your fingertips. Pick it up when your fingers stiffen, put it down when you’re back on the keys.

Warm up between tasks
Cup it for a minute, then get back to the keyboard with fingers that move.
Splits in two
Two magnetic halves: one for each hand, or one stays on the desk.
Comes home with you
Drop it in your bag at the end of the day.

So don’t wear one.
