Lexol is fine for Coach glove-tanned leather.
Don’t overthink it. Glove-tanned leather is full-grain, vegetable-tanned, and pretty tough. It doesn’t need fancy boutique stuff.
For cleaning: get a bottle of Lexol Leather Cleaner (the pH-balanced one) or a mild saddle soap like Fiebing’s. Dampen a soft cloth, work up a little lather, wipe the bag down gently, then wipe off residue with a damp cloth. Let it dry naturally.
For conditioning: Lexol Leather Conditioner is the safe bet. It’s light, doesn’t darken most leathers, and won’t clog the pores. Apply sparingly — a pea-size drop on a cloth, rub it in, buff off excess. If the bag is dry, do it twice, but rarely more.
What I’d avoid: mink oil, neatsfoot oil, coconut oil, any heavy greases. Those darken glove-tanned leather and can make it greasy permanently. Coach’s own cleaner is fine too, but overpriced for what it is.
One more thing: test any product on a hidden spot first. Glove-tanned leather can be thirsty, and different batches react differently.
