My back used to be the first thing to go cold on my 6am walks. Now I plug in, hit Low, and stay out an extra 30 minutes without thinking about it.
John M.
Tired of wearing three layers and still feeling stiff on the job site. This goes under my jacket, my arms move freely, and the warmth is right where I need it.
Robert L.
Thought it would be complicated, but it took a minute. Plug in my power bank, hold the button, done. Tap to change the heat.

No. The vest has a USB cord inside a zippered pocket, and you connect it to a USB power bank
Which power bank should I use?
Use one with a higher power output: the higher the output, the stronger the heat. Examples: 10W (5V/2A) or 22.5W (5V/4.5A)
How long does one charge last?
It depends on your power bank’s capacity and the heat level you choose. A larger-capacity power bank keeps it running longer
How do the controls work?
Hold the chest switch for 3 seconds to start, then tap to switch between Low, Medium and High. Hold again (or unplug) to turn it off.
Is it safe to wear?
It runs on USB power from your power bank and stops heating as soon as it’s unplugged.
What size should I order?
Sizes run small. Compare your chest measurement to the size chart, and if you’re between sizes, size up.
Can I machine wash it?
Yes, it’s machine washable (86°F / 30°C). Unplug the power bank first.
 
 
Just Add a Power Bank
The vest comes with its own USB cord. Plug it into a power bank and you’re warm. A higher output means stronger heat, and a larger capacity keeps it going longer.
Power bank sold separately.

When Layers Aren’t Enough
You’ve added the sweater, then the jacket, and you’re still cold. More layers hold your warmth, they don’t make it. This vest adds heat across your back, front and collar, and you choose how much.

The cold used to go right through my clothes. I can actually feel the warmth around my chest now, which is really nice.
