Simply plug a battery or power bank into your heated apparel. Ultra-thin carbon fiber elements heat up key areas, and you can control the warmth with a single built-in button.
When powered by the Koltrast Power Bank, designed specifically for our heated apparel, you can expect up to 8 hours of warmth on low, 6 hours on medium, and 4 hours on the highest setting.
Yes. The heated vest is designed as a mid-layer and works best when worn under a jacket or shell. This helps trap heat and improves overall warmth efficiency.
No. The vest has a slim, lightweight design that allows for full mobility and comfortable layering without restricting movement.
The heating zones are strategically placed to warm the core areas of the body, including the chest, back, and neck, helping maintain body temperature in cold conditions.
No. The heating system operates silently, with no noise or vibration, making it ideal for everyday wear.
Heated gloves are gloves or mittens with built-in heating elements powered by rechargeable batteries. They provide active warmth and keep your hands warm even in very cold conditions, unlike traditional winter gloves that rely only on insulation.
Heated gloves use integrated heating wires that distribute warmth across the fingers and the core of the hand. Adjustable heat settings allow you to control the temperature depending on weather and activity level.
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.
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.
Yes. Heated gloves are especially helpful for people who suffer from cold hands or reduced circulation, as the active heat helps maintain warmth for longer periods.
For anyone who spends a lot of time outdoors in winter, heated gloves are a worthwhile investment that provides better comfort, warmer hands, and fewer interruptions due to cold.
