Here is what you need to start:

1. Miller Welding Harness Gen II - https://www.acklandsgrainger.com/en/product/HEADGE...

2. Sewing Machine

3. About 16 inches of 1 3/8" Elastic (the Firmer the Better)

4. Around 6" of Velcro at least 1 3/8" wide (The Stronger the Grip, the Better)

5. A pair (2) of 1 3/8" D-rings

Elastic, Velcro, and D-rings can usually be found at your local fabric store. The current Vive headset accommodates 1 3/8" straps so there isn't anything changed that will alter the headset directly. This will help quickly change out the existing harness and still keep your warranty intact.

Do yourself a favor and get the firmest (least stretchy) elastic you can. This helps immensely in keeping the headset in place. This can also be said for the Velcro. The higher grade, the better quality of your product.
