I got this one from Amazon:

33FT PE 3/8 Inches (10 mm) Black Polyethylene Spiral Cable Wire Wrap https://www.amazon.com/dp/B07BKB4HHZ

Not saying that was the best one, it was just the cheapest black one with fast shipping at the time (you want black because it's more UV resistant). Installing it is a pain, I finally did it by dangling the cord and the wrap out a second-story window so they wouldn't get tangled up on each other.
