SAVIOR HEAT or SNOW DEER?
If you have shopped for heated socks or glove liners you have seen both of these brands, probably next to each other, at similar prices. Here is what actually separates them once you read the specifications.

They are closer than the branding suggests: both run 7.4 V packs in the same 2,200 mAh class, both offer three settings, both sell a button version and an app version. SAVIOR's range is broader — liners, gloves, mittens and socks on one pack family — while SNOW DEER concentrates on socks and iterates them. Buy on the format you need, not the badge.
Two brands, one platform
The first thing to understand about this comparison is how much the two have in common. Both sell heated extremity gear built around a 7.4 volt lithium pack that clips at the cuff or the calf, in the 2,200 milliamp-hour class — about 16.3 watt-hours per hand or foot. Both run three settings. Both publish a maximum temperature and, in most listings, a runtime range.
That is not a coincidence and it is not copying. It is what the format allows. There is a hard limit on how much battery a person will accept strapped to their ankle, and both brands have found it. Anybody promising dramatically more from the same shape is either using a bigger pack you will notice or quoting a number at a different voltage.
Where they actually differ
| SAVIOR HEAT | SNOW DEER | |
|---|---|---|
| Range covered | Liners, gloves, mittens, socks | Socks, with gloves and mittens alongside |
| Pack class | 7.4 V, 2,200 mAh — about 16.3 Wh | 7.4 V, 2,200 mAh — about 16.3 Wh |
| Spares sold as | A pair, on their own listing | A pair, on their own listing |
| App control | On the socks | On the socks |
| The strength | One pack family across four formats | Iterates the sock and publishes more sock detail |
| The weakness | No wattage published anywhere | No wattage published anywhere |
Neither brand publishes a draw figure for any product. That is normal for the category and it is the reason the runtime column on this site is frequently marked not derivable rather than filled with an estimate.
The single practical difference worth paying for is the range. If you buy SAVIOR liners and SAVIOR socks, you are inside one pack family — spares are interchangeable within the format, chargers are the same, and a second set of packs covers more of your gear. If you only ever want socks, that advantage disappears entirely and SNOW DEER's deeper sock line is the better place to shop.

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.
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.

SNOW DEER Heated Socks, 7.4V
The reference point for the category, and the rare heated product whose pack capacity is actually published — on the replacement-battery listing, if not on the sock's own page.
#ad Price as of October 17, 2026. How we are funded.
The numbers
- Energy
- 16.3 Wh
- Pack
- 7.4 V, 2,200 mAh per sock
- Element
- Toe box
- Wash
- Machine, battery out
- Heat zones
- Toe box only

- Machine washable with the battery removed
On wattage: No published wattage. The pack capacity is published on SNOW DEER's own replacement-battery listing, which gives you the energy figure even though the sock page does not.
What we like
- The element sits over the toes, which is the only place foot heat actually matters
- Replacement packs are cheap and easy to find, which extends the useful life a long way
- Machine washable, unlike most heated gloves
What we do not
- Cuff packs are visible above a low boot
- About 16 Wh a foot is not much energy
- No wattage published
Who this suits
Hunters, ice anglers, spectators — anyone standing still on frozen ground.
Who should skip it
Your boots are already tight. A sock with an element and a cuff pack needs room you may not have.

SAVIOR HEAT Heated Socks with App Control
App control sounds like a gimmick until you are laced into a ski boot and the only alternative is undoing everything to press a button you cannot reach.
#ad No live price available, so we show none. How we are funded.
The numbers
- Energy
- 16.3 Wh
- Pack
- 7.4 V per sock
- Control
- Bluetooth app plus cuff button
- Fabric
- Carbon-fiber element in a knit sock
- Heat zones
- Toe box
- Settings
- Three, with temperatures published: 104-113°F, 122-131°F and 131-149°F
- Care
- Machine washable with the battery removed
On wattage: Not published, but derivable — which is the whole reason this sock leads the page. 16.3 Wh across the published 2.5-3 h on high is about 5.4-6.5 W, across 5-6 h on medium about 2.7-3.3 W, and across 9-10 h on low about 1.6-1.8 W. The hours in the table are the low end of each published range, so the implied draws are the upper bound. A smooth descending ladder from one pack size is what a calculated spec sheet looks like rather than an invented one.
On the pack: 7.4 V, 2,200 mAh per foot — about 16.3 Wh. SAVIOR publishes both numbers, which is more than Lenz does for a sock costing four times as much.
What we like
- Adjusting from your pocket is the single most useful feature on a heated sock
- Finer control than three fixed settings, which stretches the runtime
- Still works as a normal button sock if the phone dies
What we do not
- Bluetooth is one more thing to fail in the cold
- Phone batteries drain faster in the cold too
- No wattage published
Who this suits
Skiers, and anyone whose boots make the cuff button unreachable.
Who should skip it
You do not want an app on your phone for a pair of socks. That is a reasonable position.

SAVIOR HEAT Heated Ski Mittens
Physics before electronics: fingers sharing one chamber lose less heat than fingers in separate ones, so a mitten gets more warmth out of the same watt-hours than a glove does.
The numbers
- Energy
- 16.3 Wh
- Pack
- 7.4 V, 2,200 mAh per hand — about 16.3 Wh
- Capacity conflict
- SAVIOR's own Tech Specs says 3,000 mAh instead
- Coverage
- Full hand including palm, per SAVIOR
- Shell
- Waterproof and windproof; 100D twill with laminated coating
- Format
- Mitten
- Heat zones
- "Full-Hand Heating Coverage" from "Carbon fiber heating elements", with "Added palm heating" as well as the back of the hand, per SAVIOR
- Settings
- Three, published as Low 104-113°F, Medium 122-131°F and High 131-149°F
- Care
- "Hand washing is recommended, and the battery should be removed before cleaning", per SAVIOR
On wattage: Not published, and barely derivable — this is the worst-documented product this site recommends first anywhere. SAVIOR's own page gives THREE different runtime sets and TWO different capacities. Taking the hours above against 16.3 Wh gives about 6.5 W high, 2.7 W medium and 2.0 W low; swap in the Tech Specs hours (2-3 / 5-6 / 10-12) or the 3,000 mAh figure and the implied low-setting draw moves between about 1.4 W and 3.7 W. A 2.7x spread, entirely from one manufacturer page.
On the pack: 7.4 V, 2,200 mAh per hand — about 16.3 Wh — which is the figure in SAVIOR's own body copy and matches the replacement-pack listing. SAVIOR's Tech Specs block on the SAME page says "7.4V 3000mAh battery" instead, which would be 22.2 Wh. We use the smaller figure because it is the one two independent sources agree on, and we flag the disagreement rather than averaging it.
What we like
- Mitten geometry keeps fingers warmer at any given power level
- Better for circulation-limited hands than a fingered glove
- Same pack family as the rest of the SAVIOR line
What we do not
- You cannot do anything precise in them
- SAVIOR's own page contradicts itself on capacity (2,200 vs 3,000 mAh) and gives three different runtime sets
- No wattage published, and the runtime conflict makes it hard to derive one
- Getting them on and off around a pole strap is a fiddle
Who this suits
Skiers and anyone whose hands go numb regardless of what they wear.
Who should skip it
You need to hold a tool, a camera or a phone.

The energy, brand by brand
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 Glove Liners | 2,200 mAh | 7.4 V | 16.3 Wh | Not published | Not derivable | No claim published |
| SNOW DEER Heated Socks, 7.4V | 2,200 mAh | 7.4 V | 16.3 Wh | Not published | Not derivable | No claim published |
| SAVIOR HEAT Heated Socks with App Control | 2,200 mAh | 7.4 V | 16.3 Wh | Not published | Not derivable | 6.5 Wat 2.5 h high (131-149°f) |

| SAVIOR HEAT Heated Ski Mittens | 2,200 mAh | 7.4 V | 16.3 Wh | Not published | Not derivable | 6.5 Wat 2.5 h high, 149°f / 65°c |
| SNOW DEER Upgraded Heated Socks | 2,200 mAh | 7.4 V | 16.3 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 table is the honest summary of this whole comparison: the rows are nearly identical. Both brands are selling the same energy budget in slightly different fabric. Which means the decision comes down to format, fit and price on the day, and anyone telling you one of these brands is dramatically warmer than the other is describing a difference the published figures do not contain.
What the app versions actually change
Both brands sell an app-controlled sock at a premium, and it is worth being clear about what you get.
- Per-foot control. Genuinely useful if one foot runs colder than the other, which is common and which a shared button cannot address.
- Finer steps than three. The button versions give you three settings. An app can give you more, which matters at the low end where you are trying to stretch a small pack.
- Control without undressing. Reaching a calf button under a ski boot and a trouser leg is a real annoyance the app removes.
- A phone dependency. Cold kills phone batteries, gloves make phones awkward, and Bluetooth pairing is one more thing to fail at the top of a lift. The button never fails to pair.
None of that is more heat. It is the same pack and the same element with a different interface on top. Worth it if the per-foot control solves a problem you actually have; not worth it as a general upgrade.
The thing both brands leave out
Neither publishes a wattage. Not for the socks, not for the gloves, not for the mittens, not anywhere we could find.
That matters because a runtime claim without a wattage cannot be checked. "Up to 6 hours" is a statement about a setting, a starting temperature and an ambient condition that the listing does not specify. With a published capacity, at least you can invert the claim and see what draw it implies — which is what wattage explained walks through. With neither figure, you are trusting a sentence.
This is not a criticism unique to these two. It is the category. We mention it here because these are the two brands most people in the market will end up choosing between, and it is worth knowing that the choice is being made with less information than the packaging implies.
Which to buy
- You want socks and only socks — either, and buy on fit and price. SNOW DEER's sock line is deeper if you want to compare versions.
- You want warm hands and warm feet — SAVIOR, for the single pack family across liners, gloves, mittens and socks.
- You want maximum dexterity — SAVIOR, because the liner format is the strongest thing either brand makes. See heated glove liners.
- You want the warmest possible hands and do not need fingers — SAVIOR's mittens, and read gloves versus mittens first.
- You have one foot colder than the other — the app version from either, which is the one case where the premium buys something a button cannot do.
What we would skip, and why
- Choosing between them on the temperature number
- Both brands quote a maximum element temperature and both numbers are in the same range. Peak temperature is the easiest specification to hit and the least useful to know — it tells you nothing about how long that temperature is held, which is the thing you actually experience. Capacity and output current decide that, and they are published far less often.
- Assuming the app model is the better model
- Both brands now sell an app-controlled version at a premium over the button version. The app adds a phone dependency and a Bluetooth pairing to a garment whose job is to be warm, and in cold-weather use a phone battery is its own problem. It is a genuine convenience for some people, but it is not more heat.
- Buying either as a fix for a circulation diagnosis without reading up first
- Both brands' socks are ordinary consumer heated socks. They are not medical devices, neither brand claims they are, and neither should be treated as treatment for neuropathy or a vascular condition. Heated socks for neuropathy covers what these can and cannot do.
Our criteria, and what we did not do
- Judged on what each brand publishes, because in this price class the willingness to state a capacity is the clearest quality signal available.
- Capacity converted at nominal voltage into watt-hours, the same arithmetic used everywhere here.
- Pack interchangeability checked, since both brands sell the same 7.4 V class and spares are the real running cost.
- App features counted as features, not as heat. They change the interface, not the energy.
- We have not worn anything from either brand. How we work.
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
- Is SAVIOR HEAT or SNOW DEER better?
- Neither, on the published specifications — both run 7.4 V packs in the same 2,200 mAh class with three settings, which is about 16.3 watt-hours per hand or foot. SAVIOR covers more formats on one pack family; SNOW DEER concentrates on socks. Buy for the format you need.
- Are SAVIOR and SNOW DEER batteries interchangeable?
- Do not assume so. Both use 7.4 V packs in the same capacity class, but connector shape and polarity are not standardized in this category and a plug that physically fits is not proof it is wired the same way. Buy the pack the brand sells for your product.
- Do heated socks from either brand last a full day of skiing?
- Not on high. About 16.3 watt-hours per foot is a small budget, and at a setting you can clearly feel you are looking at hours rather than a day. On low, with a boot doing most of the insulating, both brands' claims run considerably longer. Carry a charged spare pair.
- Is the app version worth the extra?
- Only for per-foot control, which is a real benefit if one foot runs colder, and for adjusting without reaching a calf button under a ski boot. It is not more heat — same pack, same element, different interface — and it adds a phone and a Bluetooth pairing to a cold-weather garment.
- Do either of these brands publish a wattage?
- No. Neither publishes a draw figure for any product we could find, which means their runtime claims cannot be checked against anything. That is the category norm rather than these two being unusual, but it is worth knowing before you compare claims across listings.
- Which brand is better for hunting?
- SAVIOR, narrowly, because hunting usually means hands and feet rather than one or the other, and a single pack family covering liners, mittens and socks is simpler to keep charged. See heated gloves for hunting and heated socks for hunting.
