We recommend doing as little care as possible as our leather is treated with oils and waxes to make it maintenance-free. It is not considered waterproof even though it has a small number of water-repellent waxes in the mix. This means that it would be fine in a drizzle or light rain but it shouldn't be left underwater or soaked intentionally.
With this said, we wouldn't recommend any conditioning or treatment unless you have a special requirement. If you still want to try and apply something for a special requirement, we typically suggest you do so over a small and discrete spot on your product to test the appearance of it before applying it all over.
