Where DEWBU Started
DEWBU was inspired by Dubu — the Swahili word for bear, a symbol of strength, endurance, and survival in extreme cold.
We build heated apparel for a simple reason: to make cold weather hurt less for the people who have to work through it. Not by adding more bulk, but by adding smarter heat.

We start with workwear because work is the real test. If a heated jacket can hold up through a long workday, a freezing early morning, or a cold night shift, it can hold up through almost any winter. The job site is the most honest testing ground there is. It asks one question: can this jacket help me get through today?
That is where every DEWBU product begins. Once a jacket works on the job, it works anywhere else cold finds you — sitting in a hunting blind, riding to work before sunrise, standing on the sidelines, or getting through a full day in a cold office.
That is what DEWBU is built for: heat that performs, protection that lasts, and a jacket you can count on.

A heated jacket is a textile, electrical, electrochemical, and human-factors product in one. Most brands treat it like apparel. We treat it like electronics — because that is what the heating system actually is.
The choice to build on 12V is deliberate. Low-voltage systems can warm a single zone. 12V gives us the power headroom to heat the core, back, and arms simultaneously — and sustain that output in wind chill, subzero temperatures, and the conditions where heat loss is fastest. It also means faster warmup: users feel warmth within seconds of switching on, not minutes.

DEWBU's engineering team covers eight disciplines: textile, electrical, thermal, ergonomics, embedded systems, UI/UX, software, and quality assurance. The thermal engineer maps heat-zone placement to where the human body loses warmth fastest. The ergonomics engineer makes sure that placement does not restrict movement. The embedded engineer writes the firmware that controls it all. Every discipline has a direct impact on how the jacket performs when you need it most.

We validate every system in the field before it ships — on construction sites, loading docks, and early-morning hunts in sub-zero wind. The goal is simple: if a jacket holds up in the places where heat loss is fastest and gear takes the most abuse, it will hold up wherever you take it.
We invest heavily in R&D and intellectual property. Our heat control and safety technology is built in-house, and we have filed a US utility patent for our proprietary Intelligent Control Circuit and Heating Garment (App. 19/369,407) to protect the engineering work behind it.
