8K FlexWarm Heated Jackets & Vests

What Makes FlexWarm Different

Most heated jackets route warmth through wire elements you can feel as firm lines across your back and chest. FlexWarm uses a thin, bendable heating film that spreads heat over a broader area and moves with the fabric, which is why these jackets feel more like ordinary outerwear than gadgets. They run on standard 5V USB power banks, so charging and swapping batteries is as easy as topping up a phone.

Jacket versus vest

The full heated jackets warm your core and arms with a removable hood for changing weather, while the gilet vest heats the torso alone and layers easily under a shell. Choose the jacket for standalone warmth and the vest for layering. Browse more core-warming options in our heated jackets collection.

5V USB convenience

Because FlexWarm runs on the same 5V power banks that charge your phone, you're never hunting for a proprietary battery. Any decent USB battery keeps you warm through the day.

Complete the warm layers

A heated jacket handles your core; heated extremities finish the job on the coldest days. Pair one with our heated gloves and heated socks for full coverage.
