ONA Leather Cream

Full-grain leather dries out, and a bag that lives in a car or a case dries out faster. ONA's leather cream is what they specify for their own bags and straps: triple-filtered beeswax with a blend of seed oils and natural lipids, worked in to condition, protect and bring back leather that has gone stiff or pale at the corners.

One 4 oz tin goes a long way on a Bowery or a Presidio strap, and it is worth keeping in the kit alongside the bag rather than buying after the leather has already cracked. Made in the USA.
