Of all the components in a quality saddle, none is more important than the leather, and Brooks carefully examines every single piece of leather ensuring that it's the absolute highest quality. For example, while it's important that all stretch is eliminated, the flexibility of the leather must remain intact so that it can conform to the contours of your body and keep its shape for years to come. Plus, thanks to the built-in pores in its fine leather, Brooks saddles have natural ventilation and never become clammy and are always cool to ride providing top levels of comfort on even the longest rides on the warmest days. Even better, plenty of Brooks customers have used the same Brooks saddle for 30 or more years, a testament to Brooks' craftsmanship and the fine materials in their saddles.
