Heated ski gloves, where geometry beats battery
A mitten gets more warmth out of the same watt-hours than a glove does. On a lift day, that matters more than any specification.

For skiing, a heated mitten beats a heated glove with the same pack, because five fingers sharing one chamber lose less heat than five fingers in separate ones. Packs here run about 16 to 24 watt-hours a hand, and a cold lift day reduces usable lithium capacity further — so format and spare packs matter more than headline specs.
The mitten argument, made properly
Heat loss scales with exposed surface area. A gloved hand presents five separate cylinders to the air, each with its own surface losing heat independently. A mittened hand presents one larger, rounder mass with substantially less surface for the same volume — and the fingers inside are warming each other rather than each fighting alone.
This is why mittens have outperformed gloves in cold-weather clothing since long before anyone put a battery in one, and adding electricity does not change the underlying geometry. A heated mitten and a heated glove carrying the same pack are not equivalent products.
The counter-argument is dexterity, and on a ski day it is weak. You need to hold a pole, work a buckle and occasionally hold a phone. Everything else — the lift, the descent, the lift queue — asks nothing of your individual fingers.

Gerbing 7V S7 Heated Gloves
Two 3,400 mAh packs is the largest per-hand energy figure on this list, and it still will not get you a full day on high — which tells you most of what you need to know about heated gloves.
#ad No live price available, so we show none. How we are funded.
The numbers
- Energy
- 23.8 Wh
- Pack
- 7 V, 3,400 mAh per glove
- Packs included
- Two, plus a dual charger
- Element coverage
- Full finger
- Heat zones
- Back of hand and along all five fingers
- Settings
- Three
- Care

On wattage: Gerbing publishes no wattage. It does publish pack capacity and voltage, which is more than most glove makers do and enough for the energy half of the arithmetic.
What we like
- The element runs the full length of the fingers, not just across the back of the hand
- Largest published per-hand capacity here
- Ships with both packs and a dual charger, so there is nothing else to buy
What we do not
- No published wattage, so the runtime half of the sum is unavailable from Gerbing alone
- Bulky enough that fine work is awkward
- Expensive
Who this suits
Motorcyclists and anyone whose hands sit in moving air, where the heat is fighting convection rather than still cold.
Who should skip it
You need dexterity. These are warm mitts with fingers, not working gloves — look at liners instead.

SAVIOR HEAT Heated Glove Liners
The most underrated format in heated apparel: a thin heated liner under your existing work glove beats a bulky heated glove for anyone who has to actually use their hands.
#ad No live price available, so we show none. How we are funded.
The numbers
- Energy
- 16.3 Wh
- Pack
- 7.4 V, 2,200 mAh per hand
- Thickness
- Liner — fits inside a work or ski glove
- Touchscreen
- Yes, per the listing
- Heat zones
- Back of hand and fingers
- Settings
- Three
- Care
- Hand wash with the battery out
On wattage: No published wattage. Small packs and a small element area, so the runtime spread between settings is wide.
On the pack: Liner packs in this class are 7.4 V, 2,200 mAh. The capacity is stated on the replacement-pack listing rather than on the glove listing.
What we like
- Fits under gloves you already trust, so you keep your grip and your dexterity
- Cheapest route into heated hands by a wide margin
- Packs are small enough to live in a coat pocket
What we do not
- Smallest packs here — about 16 Wh a hand, and the arithmetic on that is unforgiving
- No wind or water protection of their own
- The fit under a tight glove can be a squeeze
Who this suits
Trades workers, photographers, anyone who has to do something with their fingers in the cold.
Who should skip it
You want long runtime. This is the smallest energy budget on the site and it shows.

Cold makes the battery smaller
There is a second-order effect on a ski day that most buyers do not plan for. Lithium cells deliver less usable capacity when cold, and a pack strapped to the outside of your wrist on a chairlift is very cold indeed.
So the watt-hour figures below are a room-temperature ceiling, not a promise. The practical consequences: buy a model with cheap replaceable packs, keep the spares in an inside jacket pocket rather than a shell pocket, and expect the second pack of the day to outperform the first because it started warm.
Watt-hours, and what they buy
Energy is capacity times nominal voltage. The ceiling draw is the pack’s own published output current times its voltage. The implied draw runs the maker’s advertised hours backwards. Nothing here is measured — check our working.
| Product | Capacity | Volts | Energy | Ceiling draw | Shortest runtime | Implied draw at the claim |
|---|---|---|---|---|---|---|
| SAVIOR HEAT Heated Ski Mittens | 2,200 mAh | 7.4 V | 16.3 Wh | Not published | Not derivable | No claim published |
| Gerbing 7V S7 Heated Gloves | 3,400 mAh | 7 V | 23.8 Wh | Not published | Not derivable | No claim published |
| SAVIOR HEAT 7.4V Heated Gloves | 2,200 mAh | 7.4 V | 16.3 Wh | Not published | Not derivable | No claim published |
| SAVIOR HEAT Heated Glove Liners | 2,200 mAh | 7.4 V | 16.3 Wh | Not published | Not derivable | No claim published |
| Gerbing 7V Women's S7 Heated Gloves | 3,400 mAh | 7 V | 23.8 Wh | Not published | Not derivable | No claim published |
“Not derivable” means the manufacturer does not publish the figure the sum needs. We leave it blank rather than estimating it, borrowing a number from a similar model, or rounding one into existence. These are ceilings, not promises: cold, wind, movement and pack age all push real runtime below them. Run your own numbers.
The cuff decides whether any of this matters
Snow entering at the wrist will make your hands cold faster than any element can warm them, and once the liner is wet, the element is trying to heat water. A long gauntlet over the jacket sleeve, or a tight elasticated cuff under it, is not an accessory question — it is the difference between the product working and not.
This also decides the liner question for skiing. A liner inside a proper ski glove gets you the ski glove's gauntlet, waterproofing and fit. That is a strong combination, and if you already own gloves you like, it is a cheaper route to the same place than replacing them. Heated glove liners covers the format.
What we would skip, and why
- A heated glove chosen over a heated mitten purely for the finger count
- Five fingers in five separate chambers each lose heat independently. The same fingers in one shared chamber warm each other. That is a design advantage no amount of extra battery buys back, and on a lift day, where you barely need individual fingers, the mitten is simply the better product.
- Any heated glove without replaceable packs, for skiing specifically
- A ski day is long, cold and hard on lithium. Cold reduces usable capacity, and a full day of lift-and-run will outlast one pack. A glove you cannot re-pack is a glove that is cold by mid-afternoon on precisely the days you bought it for.
Our criteria, and what we did not do
- Format weighted above capacity. Mitten geometry does more for warmth than the differences in pack size do.
- Cold-weather capacity loss acknowledged, because a ski day is exactly where lithium underperforms its rating.
- Cuff and gauntlet length recorded — snow entry at the wrist undoes everything the element does.
- We have not worn any of these or skied in them. See how we do this.
We have not worn, tested or owned any of these products, and we say so on every page rather than in a footer. What we do instead is compile the published specifications and do the arithmetic. The full method.
Frequently asked
- Are heated mittens better than heated gloves for skiing?
- Generally yes. Five fingers in one shared chamber lose less heat than five in separate chambers, and skiing asks very little of individual fingers. You give up dexterity you were not really using on the hill.
- How long do heated ski gloves last on the mountain?
- Less than the room-temperature figure, because cold reduces usable lithium capacity. The packs here hold 16 to 24 watt-hours a hand at rated capacity; makers do not publish the draw, so we mark the exact hours not derivable. Plan on spare packs kept warm in an inside pocket.
- Can I wear heated liners inside my existing ski gloves?
- Yes, and it is a strong combination — you keep the ski glove's gauntlet, waterproofing and fit, and add heat. The only requirement is room. Forcing a liner into a snug glove restricts circulation and makes things worse.
- Do heated gloves work in a ski boot day of -10C?
- They help, but expect meaningfully shorter runtime than the rated capacity suggests, because cold cuts what a lithium pack can deliver. Carry a warm spare pack and swap it at lunch rather than waiting for the first one to die on the last run.
- What should I look for in a heated ski glove?
- A long gauntlet or a genuinely sealed cuff first, because snow at the wrist beats any element. Then cheap replaceable packs, then element coverage. Zone marketing and headline runtime figures matter less than all three.
