BUILT BY RIDERS WHO REFUSED TO CHOOSE

GripHeat started in a parking lot in January, somewhere on Colorado's Front Range, with two riders staring at their hands. The bikes had heated grips — good ones, cranked to full. The gloves were serious winter gloves, the kind that make your levers feel like rumors. And the fingers inside were still blocks of ice.

That's the deal every cold-weather rider has been offered for decades: frozen fingers, or hockey mitts. Feel the bike and suffer, or stay warm-ish and ride numb. We'd both taken that deal for years. That morning we got curious about why it exists at all.

Heated grips throw off real wattage. But a winter glove is an insulator by definition — it can't tell the difference between the cold it's supposed to keep out and the heat it's supposed to let in. All that energy stops at the palm padding and radiates uselessly back into the Colorado air.

So we stopped trying to add more heat and started trying to move the heat that was already there. The material answer turned out to be old physics: silver, one of the best thermal conductors known, woven as thread through an ultra-thin liner. Palm side picks heat off the grip; the weave carries it across the fingers and the back of the hand. Two winters of prototypes, a lot of frostbitten test loops, and one 0.4mm liner later — GripHeat.

We're still a small crew. We still ride to work in February. And we still believe the best gear is the kind you forget you're wearing.
