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 |

Customer reviews
What verified FibreHeat buyers say about staying warm, without batteries or charging.
Living with Raynaud's
If you live with Raynaud's, you know the feeling — white fingertips in the freezer aisle, numb toes on a mild day. FibreHeat's warmth is built into the fabric, so it's there the moment you put it on and stays gentle and steady all day.
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.
“I suffer from Raynaud's, which has gotten progressively worse over the years. Your gloves have prevented my fingers from turning white, even in extreme cold and refrigeration at the grocery stores.”
FibreHeat is not a medical device and is not intended to diagnose, treat or cure any condition. If you have Raynaud's, speak to your doctor about managing your symptoms.

Every piece uses the same heat-generating fiber. No batteries, no charging — just put it on.
Questions, answered The six we hear most
How FibreHeat keeps you warm without a battery, and where its limits are, answered as plainly as we can.
The warmth comes from the yarn itself. Heat-returning fibers are knitted into the fabric to hand your body’s own heat back to your skin, so less of it escapes into the cold. There is nothing to switch on, because there is nothing electrical in it.
You should notice a gentle warmth building soon after you put them on. It isn’t the hot-plate feeling of a heated glove. It is steadier and quieter, more like a warm hand around yours.
As long as you’re wearing it. There is no charge to run down, so the warmth doesn’t fade halfway through the commute or the dog walk. Take them off, put them back on, and they pick up where they left off.
Check the care label, because it depends on the piece. Our glove liners, socks, base layer shirt and throw are machine washable: cold, delicate cycle, no bleach, tumble dry low. Our gloves, mittens, hats and neck warmers are dry clean only. Either way there are no wires or batteries to take out first.
That is exactly what they are for. The liners are thin enough to slip under ski gloves, work gloves or a favorite leather pair, adding warmth without changing how they fit.
FibreHeat isn’t a medical treatment, and we won’t pretend it is. What it offers is gentle, steady warmth you can wear all day, which is what many people with cold hands look for. If you have Raynaud’s, talk it through with your doctor too.
