Hestra's all-natural Hestra Leather Balm is formulated to protect your sport gloves and is a great way to prevent leather from drying out. Prolongs the life, suppleness and water repellant properties of the leather. Apply as needed with a polishing cloth, rub in until the leather is saturated. Note that light leathers may darken somewhat. Hestra Leather Balm is a leather conditioner, it is not a dedicated leather waterproofing agent. We recommend only using our leather balm for our sport gloves in goat leather or cowhide leather. Other leathers such as deerskin, elk leather, peccary, carpincho and hairsheep which are more common in our fashion gloves are oftentimes not suitable to be treated with leather balm. These leathers do not absorb the balm very well and thus may leave a sticky surface and also cause the leather to look mottled with color variations.
