Nothing fits better than a worn pair of gloves. The problem is when those favorite leather or fabric gloves get a little worn and fail to keep your hands dry and warm. One great way to extend the performance of your gloves is with the Nikwax Glove Proof, a special conditioner that restores and adds water-repellency to leather and fabric gloves. One 4.2 oz. bottle might even last longer than your gloves.
