Choosing the Correct Size

  1. Make sure you are wearing only a t-shirt
  2. Measuring your chest (just under the arms), and then your stomach
  3. Take the larger of these two measurements as your reference point
  4. A 42 size vest is a good fit for a person with a 42-inch reference point (when worn properly the vest should hug the contours of your body)

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. See the last picture to get an idea of how this would look on you!




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 Diagram

      If you own other pieces of GEARS heated clothing, you can easily add this to your setup! The diagram below illustrates how to connect our heated clothing seamlessly. Gen-X3 and Gen-X4 are compatible with one another. Note that the heated jacket in the diagram below can be swapped with the heated vest.

      Seamless Connectivity for Heated Clothing

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


      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!


      Q: What are the specs?

      A: The specs vary depending on the size.

      Size 34: Provides 40.8 watts of heat and draws 3.4 amps of current

      Sizes 36 - 52: Provides 48 watts of heat and draws 4 amps of current
