“I mainly switch it on when I stop moving.”
I bought it for trips and waiting outside. The big advantage is being able to add heat as soon as you start to feel the cold.
Customer reviews
As long as you are moving, your body generates heat on its own. It is when you stop – on the platform, in the queue, on the sidelines – that wool no longer has any warmth to hold on to. Ridge 21 adds warmth instead: one press, and you feel it after ten seconds in your neck, back and chest.

Tested through 300 wash cycles – gentle cycle at 86 °F (30 °C), battery removed: the system is built to last several winters.

I leave at 6:40, the bus stop is out in the open, and I used to get to work freezing. I press the button when I leave the building, and before I’m down the street, my back is already warm. I don’t even need full power.

I’m on construction sites all day. Before, I wore three layers and could hardly lift my arms. This is a regular down jacket, I move normally, and the warmth comes when I stand still.

It was a little tight across the shoulders with a thick sweater underneath. I exchanged it for the next size up, and now it’s perfect. Choose one size larger if you’re unsure. Otherwise, I have no complaints: it keeps me properly warm without being heavy.

I ride a scooter every day, and December in Minneapolis is relentless. My upper body is no longer exposed to the wind in the same way. The battery easily lasts both trips, and I recharge it every other evening.

I'm always cold in my hands and feet, and my back stiffens as soon as the weather turns damp. I use it when I go out into the garden in the morning. The storage bag is very practical when the jacket needs to be put away for the summer.

I ordered it for my father and received it after four days. Everything was in the package, including the battery, so he did not need to buy anything else. He put it on that same day to go and buy bread and has barely taken it off since.

Two hours standing at the Christmas market without wanting to go home – that is the first time. Before, I lasted forty minutes. My friends asked where I bought it.

At first I kept it on full power all the time, so the battery naturally ran out quickly. On the low setting it lasts all day, and I am more than warm enough – it said so in the instructions, so I should have started by reading them. No problems since.

I work from home in a poorly insulated apartment and refused to turn up the heat. I sit on the sofa with it open, on a low setting. My bill has not increased this winter.

I walk the dog twice a day, whether it’s raining or freezing. This is the first jacket where I don’t need an extra sweater. It’s easy to use: one button, three settings, that’s all.

As long as you are moving, your body generates heat on its own. It is when you stop – on the platform, in the queue, on the sidelines – that wool no longer has any warmth to hold on to. Ridge 21 adds warmth instead: one press, and you feel it after ten seconds in your neck, back and chest.
How it works, in pictures
At 6:40 p.m., on the platform, in the wind: you have the right down jacket – and you are still cold because you are no longer moving. That is exactly why adjustable heat exists.
What Ridge 21 changes
A good heated garment should not feel like a gadget. It should be worn often, be clear about size, battery and care, and provide warmth when the cold really sets in.
Easy to use
Choose a size, connect the battery, then adjust the intensity according to the weather, the wait time and your activity level.
1. Connect
Place the battery in the pocket designed for it, and connect the cable.
2. Slå på og juster
One button on the chest: hold it down to start, and press to change the intensity.
3. Kjenn varmen
Heat is felt in 10 seconds: in the neck, back, upper body and arms … and your hands stay warm in the pockets.
4. Gå ut
Keep your outfit, with extra warmth when the cold sets in.
Complete box
The contents are shown before you add to cart: the down jacket, the 20,000 mAh battery, the cable and the user guide. No extras discovered only when unpacking – this is the market’s most common trap, and exactly what we refuse to subject you to.
Why the 21-zone system
When you move, the insulation is already doing part of the work. When you are waiting or the wind persists, the adjustable heat gives you extra comfort.
It insulates well, but still depends on the heat your body produces.
It is warm at first, but then you start sweating as soon as you move, and you cannot take anything off without opening everything again. The layers are fixed, while the cold changes every ten minutes.
One layer of about 600 g, with heat you can adjust: higher when standing still, lower when walking and off in the sun. You adapt the heat instead of layering up. Tested in real conditions at −9 °F (−23 °C).
