FibreHeat fibers are knitted right into the fabric. They turn your body’s natural moisture into heat, store it and return it to you, so there's nothing to charge and nothing to plug in.

03 —How FibreHeat works Field Guide · The Layers
Your body is always giving off heat and moisture. In the cold, most of that warmth simply drifts away. FibreHeat liners are knitted with fibers that turn your moisture into heat, store it in microscopic heat-packs and return it to your skin.
Because the warmth comes from the fabric itself, there are no batteries, wires or settings. It works as soon as you pull them on, and wicking keeps you warm and dry for as long as you wear them.
Warm as you put them on
Warmth starts the moment the knit meets your skin. No waiting.
Nothing to charge
No batteries, cables or plugs. Just fabric doing its job.
Thin enough to layer
Slim liners sit easily under the gloves you already own.
Made for all day
The commute, the dog walk, the whole shift outdoors.
The simple comparison
Both keep your hands warm. One asks a lot less of you.
A general comparison with typical battery-heated gloves. Individual products vary.
| FibreHeat | Battery-heated | |
|---|---|---|
| Weight | Feels like an everyday knit glove | Extra weight from packs and wiring |
| Charging | Never. There's nothing to plug in | Needs charging before you head out |
| Bulk | Slim enough to layer or wear alone | Bulkier cuffs to house the battery |
| Washing | Nothing to remove before cleaning | Battery out first, often hand-wash only |
| Wear time | Warm for as long as you wear them | Warmth ends when the battery runs down |

No batteries, no charging
Nothing to plug in, nothing to run flat halfway through your day.
Gentle, continuous warmth
Steady comfort from the fabric — no hot spots, no settings to manage.
Thin liners that layer
Slim enough to wear under your favorite gloves, or on their own.
