What Our Gearhead(R) Experts Are Saying: "I've used Proofide on every Brooks saddle I've owned. It helps break in the leather faster and keeps it from drying out. It's easy to apply, and the natural finish it leaves makes the saddle look even better over time."Every Brooks saddle tells a story, but only if you take care of it. Proofide is the essential conditioner that protects that story, softening the leather, preserving its structure, and making the break-in period smoother and more comfortable. Made from natural ingredients, Proofide is designed exclusively for Brooks leather saddles and helps shield them from moisture, grime, and wear. A light coat on the top surface soaks in and buffs to a soft luster, while an unpolished layer underneath adds water-resistant protection. Use it regularly and you'll keep your saddle looking and feeling better, mile after mile.
