How Blaze Heat Works

Every Blaze heated work jacket, vest, and sweatshirt has heating zones built into the chest and back to keep you warm when you're out in the cold.

One button. Three settings. No problem.

Simple control

One button runs the whole system; no fiddling with complicated controls. Press it to cycle through three heat settings: low, medium, and high.

LOW 8 hours of heat
MEDIUM 6 hours of heat
HIGH 4 hours of heat

Heat vs. battery life

Higher settings run warmer but use more battery; low settings stretch your charge the furthest.

All-shift power

You get up to 8 hours of continuous heat per charge cycle depending on the setting. You can even use it to charge your phone if needed.

Battery placement

The battery rides on the right side of the jackets and vest, and inside the kangaroo pocket on the sweatshirt.

Read the manual

A printed operator's manual ships with every garment, covering battery care, charging, and safe use. It's short, and it'll help you get the most out of your heated workwear.

Lightweight or Midweight?

Choose Based on How Much You Move

Moving all day: go lightweight

If you're hauling, climbing, or walking a site all shift, you make your own heat. You just need help holding onto it. The Blaze Lightweight Diamond Quilted Heated Puffer Jacket is low-bulk and built for movement, with powered heat for the slow stretches.

Standing still: go midweight

Flagging traffic, sitting in a deer stand, working a fixed post: standing-still in the cold is not for the faint of heart. The Duck Jacket and Two-Tone Puffer Jacket are midweight, built for the hours when you're not moving and the cold has nothing better to do than find you.

Layering: go vest or quarter zip

The Puffer Vest puts the same chest and back heat zones under whatever shell you already trust. The Heated Quarter Zip Sweatshirt works alone in the shop or as a heated base layer outside.

Blaze vs. Polar King:

Which One Do You Need?

Polar King is our insulated, fleece-lined collection. It traps body heat you're already making. Blaze adds powered heat zones on top of insulation, so you stay warm even when you're not moving enough to generate your own. If you're active in moderate cold, Polar King does the job. If you stand still or are exposed to serious cold, Blaze is built for you.

How Blaze Heat Works

  • Utility crews on storm restoration
  • Flaggers working in the elements
  • Farmers doing chores before sunrise
  • Hunters sitting in a stand until dark
  • Municipal and industrial workers whose shift doesn't care what the thermometer says
  • Travelers on vacation in cold weather locations
  • Families supporting their cold weather athletes (no more freezing in the stands at your child's games!)

If your job involves functioning while it's freezing, this line was designed precisely for you.

Blaze Frequently Asked Questions

An insulated jacket traps the body heat you produce; a heated jacket adds its own warmth through battery-powered heating zones. Blaze heated work jackets combine both — insulation plus powered heat panels at the chest and back — so you stay warm even when you're standing still and not generating much body heat.

Every Blaze garment has three heat settings — low, medium, and high — controlled by a single one-touch button. Press it to cycle between levels. Red is high, white is medium, blue is low. Higher settings deliver more warmth but drain the battery faster, while low extends run time. Most workers use high to warm up, then drop to low or medium.

Every piece in the Blaze collection delivers up to 8 hours of continuous heat per rechargeable charge. Actual run time depends on your heat setting. Low stretches the battery furthest, high uses it fastest. The battery sits in the right-hand pocket on the jackets and vest, and inside the kangaroo pocket on the sweatshirt. You can use the battery to charge your phone if needed, but keep in mind that this will reduce the battery life.

Yes. Blaze garments are designed for all-day wear, with one-touch control so you can adjust or turn off heat anytime. Every garment ships with a printed operator's manual covering battery care, charging, and safe use. Follow it, keep the battery charged and undamaged, and you're set for a full shift.

Choose lightweight if you're moving all day. The Lightweight Diamond Quilted Heated Puffer is low-bulk and built for high-activity work. Choose midweight if you stand still in the cold: the Two-Tone Puffer Jacket, Quarter Zip Sweatshirt, and Duck Jacket are built for jobsite shifts, flagging posts, and deer stands.

Yes. Every Blaze garment is machine washable. Just remove the battery first. Take the battery out of its pocket (right side on jackets and the vest, inside the kangaroo pocket on the sweatshirt), then wash. The printed operator's manual included with every garment has full care instructions.

Blaze garments are water resistant, not waterproof. The construction sheds light rain, snow, and drizzle so the heating system and insulation keep doing their job in typical winter work conditions. For prolonged heavy rain, you'll want a dedicated rain shell over the top.

Blaze is built for people who work outside in freezing weather without moving much: utility crews, flaggers, farmers, hunters, municipal and industrial workers, cold weather travelers, and families enjoying outdoor games and sports. It comes in five styles from a duck jacket to a heated sweatshirt, in sizes Regular S–4XL, all with chest and back heat zones.

We've been making workwear for over a century, and most of what we've learned comes down to one thing: build it for the person wearing it. Blaze has the same KEY durability your grandpa's overalls had, with a little battery power to heat things up.
