About FIBREHEAT®

Four founders. One cold-hands problem.

FibreHeat® began with four founders from electrical and textile engineering, fashion design and business development, and one question: could a fabric keep cold hands warm without a battery?

Where we started

Most performance fabrics are built for athletes: wick the sweat, cut the weight. We wondered what a heat-generating fabric could do for people whose hands and feet are always cold.

Gloves came first. We tested them in a refrigerated room with sensors on each hand, two gloves worn side by side, and FIBREHEAT® gloves outperformed everything we put them up against.

How we make them

Our knit gloves are made on high-tech knitting machines that work almost like 3D printing. They come off the machine needing next to no finishing: no sewing, and no seams.

For people with cold hands it has always been a trade-off between style and warmth. We wanted gloves that look like gloves, in merino, cashmere and leather, not like a medical device.

Who we make them for

Everyone who runs cold, and especially people living with Raynaud’s, scleroderma, arthritis, lupus and other circulation problems. We’re a proud sponsor of the Raynaud’s Association.

FibreHeat® is a registered trademark of New York Knitworks, LLC, in Eastchester, New York.

Our mission

Keep people warm with the heat they already make. No batteries. No wires.

Ultra-soft comfort

A premium blend of fibers that feels soft against your skin while providing thermal insulation.

Breathable & dry

Wicking pulls moisture away from your body, so you stay warm and dry, never clammy.

Designed to last

Quality construction means your FIBREHEAT® gear withstands the coldest days, season after season.

The technology

Patented fabric. Not a gadget.

FIBREHEAT® is our patented heat-generating textile, protected by US and European patents. Here’s what happens from the moment you put it on.

01

Intertwined fibers

Multiple different fibers are combined into one highly technical, functional textile.

02

Moisture becomes heat

The fabric starts generating heat as soon as you wear it, by converting your body’s natural moisture.

03

Stored and radiated

Heat is held in microscopic heat-packs and released as far infrared — like the sun, below the visible spectrum.

04

Wicked away

Moisture wicks away from the skin, so you stay warm and dry.
