Their sales pitch is impressive and even convincing. Their "Happy Bottoms Club" is amusing. They look good and I have the impression that a Brooks might be a bargain by comparison but I didn't see anything about an actual price.
Of particular interest to Clydesdales, I quote from their site:
Leather laminate under layer - If rider weight is close to or above 180 lbs / 82 kg we make a Clydesdale laminate at no added cost. The Traditional Saddle Leather model is available with or without our Patent Pending laminates. The non laminated model is an excellent choice for lightweight riders <125lbs / 55kg and folks who only ride once or twice a month, never in foul weather.
