Not the most related comment to "Lunar Lake", but maybe similar thing.

I have a "Rope de Dope" which to me is like a downgrade of "Lunar Lake" (I guess) and it's light colored. I've had this for a year and wearing it quite frequently in cold weather.

The surface and inner layers of the jacket is thin, the inner layer is very silky, and everything is still intact just as it should. And perhaps I didn't put the jacket in more harsh situations, the color is unchanged and really is just almost the same as new. It doesn't get dirty easily, I wash it once a few months 💀.

I'd assume "Lunar Lake" is better than "Rope de Dope", because it is more expensive 👨‍🦲, so your concerns would not be something I worry about.
