How to measure your hand
To find your size, you need to measure the circumference of your hand:

  1. Open your hand: Relax your fingers and keep your hand flat.
  2. Measure around the knuckles: Wrap a measuring tape around the widest part of your hand (across the knuckles). Do not include the thumb.
  3. Measure gently: Ensure the tape is snug but not tight against the skin.
  4. Compare: Check your measurement against the chart above.


Tip:
If you are between two sizes, we recommend choosing the larger size. This ensures proper blood circulation, which is essential for keeping your fingers warm.

Engineered for Arctic Conditions

When standard insulation fails, our active technology takes over. Powered by heavy-duty 7.4V Lithium-ion (Li-ion) and advanced alloy fiber heating elements, these mittens generate an intense, therapeutic heat of up to 57°C (135°F). By focusing the heat across the back of the hand, they warm the blood circulating to your fingertips, ensuring your entire hand stays functional and warm in biting sub-zero winds.

Warmest mitten You’ll Ever Own

Active Heat Injection

Three adjustable heat levels allow you to command your own microclimate, regardless of the external weather.

Expedition-Ready Design

Featuring a heavy-duty snow lock, toggle stoppers, and a dual-fastening system (velcro + elastic), these mittens create a vacuum-sealed environment that keeps the cold out.

Anatomy of Arctic Comfort

Our multi-layer construction eliminates the cold by uniting goat leather and 3M™ Thinsulate™ with active heat. The result is an impenetrable barrier against snow, sleet, and gale-force winds.

Frequently asked questions

How long does the battery last?

The battery life depends on the heat setting you select:

High (Red): 57°C | Approx. 2.5 hours
Medium (White/Blue): 49°C | Approx. 4 hours
Low (Green): 42°C | Approx. 8 hours

To maximize battery life, we recommend starting on High for 5–10 minutes to pre-heat, then switching to Medium or Low.

Are the mittens waterproof?

Yes. The mittens feature a high-quality PU coating and water-resistant goat leather. While they are designed to handle heavy snow and sleet, we do not recommend submerging them completely in water due to the internal electrical components.

How do I charge the batteries?

Your package includes a Dual Adapter, allowing you to charge both 7.4V batteries simultaneously. Simply remove the batteries from the glove pockets, connect them to the charger, and plug it into a standard wall outlet. A full charge takes approximately 4.5 hours.

Where exactly is the heat generated?

The heating elements (Alloy Fibre) are strategically placed along the back of the hand. This is the most effective way to keep hands warm, as it heats the blood as it flows toward your fingers, ensuring your entire hand stays warm even in extreme cold.

Can I use these mittens without the battery?

Absolutely! Thanks to the 3M™ Thinsulate™ C100 insulation and premium goat leather shell, these are exceptionally warm winter mittens even when the heating system is switched off.

Are they safe to use?

Yes, your safety is our priority. Our mittens and batteries are fully CE and ROHS certified. The 7.4V Lithium-ion (Li-ion) system includes built-in sensors to prevent overheating and short-circuiting.

How do I clean my heated mittens?
  • Do not machine wash or dry clean.
  • Remove the batteries before cleaning.
  • Spot clean using a damp cloth and mild detergent.
  • Always air dry the mittens flat.
  • Do not tumble dry or place them directly on a radiator.
