Inside the Tech: How Carbon Fiber Heating Pads Keep You Warm

There’s a big difference between feeling layered and feeling warm.

At Koltrast, we wanted to create a heated vest that feels just as natural and comfortable as your favorite outerwear - only smarter.

The secret? Carbon fiber heating technology.

The Science of Warmth, Simplified

Traditional heated clothing often relies on metal wires stitched through the fabric. They work, but they can feel stiff, uneven and not exactly elegant. The Koltrast Heated Vest takes a different approach.

Inside, there are six ultra-thin carbon fiber heating pads positioned across the chest, back, and collar. These pads produce infrared heat - a type of warmth that gently radiates through your body rather than blasting heat on the surface.

Think of it like sunlight on your skin on a cold day: soft, even and deeply warming.

Power You Already Have

No proprietary battery. No weird charger.

The Koltrast Heated Vest runs on a 5V USB power bank, the same one you use to charge your phone.

Plug it in, press the power button and choose your preferred heat level. The system is low-voltage and completely safe, delivering up to eight hours of consistent warmth without overheating or draining your battery too quickly.

It’s technical gear that feels refreshingly simple.

Warmth Where It Matters

Every heating zone in the vest is placed with purpose:

• The upper chest to keep your core temperature steady

• The lower back to prevent chill from wind exposure

• The collar to trap warmth around the neck

Each heating element is ultrathin, flexible, and tucked between soft insulation layers. You don’t feel wires or bulk, just a natural, comfortable warmth that adapts to your movement.

Built to Last, Season After Season

Carbon fiber isn’t just efficient - it’s tough.

Each heating panel is tested to endure over 10,000 bends and folds, meaning it won’t wear out after one winter. It doesn’t corrode like metal either, so performance stays consistent even after washing (just remove the battery first).

That’s part of our sustainability mindset - building gear that lasts, instead of gear that needs replacing every season.

A New Way to Experience Cold

The Koltrast Heated Vest isn’t just about staying warm. It’s about extending your comfort zone, on city commutes, mountain trails or just crisp autumn walks.

It combines Scandinavian design - clean, functional, understated - with modern wearable heating technology that works quietly in the background.
