  • Leverages ZEPTO® fibre technology; made in France, these heating fibres are so thin you wouldn't be able to notice them if not for their tremendous heat output
  • ZEPTO® fibres are lighter and heater up faster than the heating wire in our Gen-X3 line of heated clothing
  • Ergonomically designed to hug the contours of your body
  • Uniform heat delivered all over the front, back, and collar
  • Two easily accessible side pockets on the front of the vest to keep a wallet or other essentials
  • Anti-bacterial, breathable, and water-resistant fabric
  • The bottom edge of the vest lands just above the beltline thus maintaining your range of motion
  • Pairs seamlessly with our heated gloves or glove liners (see wiring tab for more info on this)

Note: Wear this vest over a t-shirt and under a jacket to maximize heat retention

    Optional Portable Battery Add-on

    Consider purchasing one of our Heated Clothing Portable Battery Kits if you'd like to use your heated vest when you get off your vehicle. In other words, a portable battery will allow you to use this vest while skiing, snowboarding, or just taking a walk on a cold day.




    Wiring – MUST READ ⚠️

    One 20" long Coax Battery Cord (SKU 100227-1) is included

    You will need ONE of the below switch cords OR temperature controllers (sold separately)


              • You will need the Snap-on Harness (SKU 100226-1) (sold separately) ONLY IF you intend on connecting  Heated Gloves or Heated Glove Liners to this vest

              IMPORTANT NOTE: Gen-X3/X4 heating clothing is not backwards compatible with Gen-X2 heated clothing. Attempting to connect this item to Gen-X2 heated clothing will ruin it and VOID the warranty. Only heating elements are covered under warranty. Normal wear and tear is not a warrantable defect.

              Seamless Connectivity for Heated Clothing

              Watch the video below for a walkthrough on connecting various pieces of our heated clothing 


              Q: What are the specs?

              A: Vest produces 53 watts of heat and draws 3.9 Amps of current (tested when the engine was idling).


              Q: Will this work alongside other brands of heated clothing?

              A: Yes! All our heated clothing is compatible with Firstgear, Gerbing, Warm & Safe, and Venture Heat. You may need an adapter such as our SKU 100386-1.


              Q: What is the difference between Gen-X3 and Gen-X4?

              A: Gen-X3 uses a copper-based heating element (made in the USA), whereas Gen-X4 uses Zepto fibres (made in France). Thus, Gen-X4 heats up faster, generates more heat, and is lighter. Both are amazing products, but Gen-X4 is just a little bit of an upgrade!
