CARE INSTRUCTIONS

Fabric:

  • Socks washable at 30°C.
  • Do not use washing powder or laundry detergent to clean the socks.
  • Always remove the batteries and heating element before washing.
  • Do not dry clean or do not use dry-cleaning fluid.
  • Do not bleach.

Battery:

Correct usage and storage of the battery will prolong the capacity and battery life.

  • Charge the batteries on a regular basis (at least every 3 months) to prolong the battery life, even during summer when the batteries aren't regularly used.
  • Use the specified charger only. Using another charger may affect the battery life and can affect your safety.
  • Always disconnect the battery if the heated clothing is not used. Batteries that stay connected will still consume a small amount of power.
  • (Re)charge the battery only shortly before actual use (e.g. overnight), as a battery still loses capacity even if it is not enabled.
  • The battery does not need to be fully charged to function. However, frequent insufficient charging over a period of weeks does result in reduction of the performance capacity.
  • Completely discharging the batteries insures extremely efficient utilization. If this does not occur regularly, the charging capability can be impaired.
  • Do not expose the battery charger to moisture. Store the batteries in a dry environment at room temperature.
  • A Lithium-Ion battery cannot be overcharged via the charging control in the battery pack. It can easily withstand an overnight stay in the socket, although it only needs 3 hours to fully load.

Frequently Asked Questions

Everything you need to know about our heated clothing

Heated clothing uses built-in heating elements powered by rechargeable batteries or powerbanks. These elements distribute warmth across key areas of the body to help maintain a comfortable temperature in cold weather.

Yes. Heated clothing is designed with controlled heating systems and safety features that regulate temperature and prevent overheating when used according to the manufacturer’s instructions.


Battery life depends on the product and heat setting. On lower heat levels, heated clothing can provide warmth for max 7 hours, while higher settings deliver stronger heat for shorter periods.


Yes. Most heated clothing offers multiple heat levels, typically low, medium, and high, allowing users to adjust the warmth depending on weather conditions and activity levels.

Heated clothing is commonly used for outdoor activities such as:


  • skiing and snowboarding

  • cycling and motorcycling

  • hiking and winter walking

  • outdoor work

  • hunting and fishing

Many heated clothing products are designed with waterproof or water-resistant materials to protect against rain, snow, and wind while maintaining breathability.


Heated clothing typically uses rechargeable lithium-ion batteries or powerbanks that can be charged using the included charger.

Yes, many heated clothing items are washable. However, the battery must always be removed before washing, and care instructions should always be followed.

Heated clothing is perfect for anyone who spends time outdoors in cold weather. This includes hunters, construction workers, outdoor enthusiasts, golfers, motorcyclists, skiers, commuters, and people with circulation issues. It's also ideal for anyone who works in cold warehouses or simply feels cold easily.

Heated clothing complements layering rather than replacing it. For best results, wear a base layer underneath for moisture wicking, the heated vest in the middle for warmth, and an outer shell for wind and weather protection. This combination provides maximum comfort and temperature control in extreme cold conditions.
