I have passport camel for 7 years now. They changed leather at some point, but it ages absolutely marvellous. Some stains are more visible on it, though (no picking up with sweaty palms in summer), but nothing that a leather cleaner and conditioner can’t solve. I love mine and found that it looks more feminene (?) and cheerful compared to dark brown.
I have a camel myself that I plan to use for 2024 and I hope it can patina like the fifth anniversary travelers notebook that they released years ago 🎉
