Actually I don't think you can condition the legacy leather. Check with coach but when I emailed them they said it was vintage leather and as such I couldn't use any products on it. It also said something like that on the care card.
Hmmmmmmmmm, the sticky on here about cleaning says you can:
The Coach Soft Legacy Collection styles should be cleaned with Coach Leather Care or Moisturizer.
I used the Moisturizer on my Legacy Leather Flap (Whiskey) and it looks awesome!
