Horse Saddle Cinches
Cinches are, of course, necessary to hold a saddle in place. The trick is to get a cinch that is comfortable for the horse but still holds the saddle firmly.
Cinches vary in width according to where your saddle is rigged and what job the horse is doing. Most 27-strand cinches will fit a pleasure horse with 7/8 or 3/4 rigging without being too wide and interfering with his front elbows. If your saddle is rigged way forward (full rigging is not very popular) you may want a 17 strand cinch. If you have a roping horse, you may want a cinch that is wider in the middle to help prevent rolling under pressure from a roped steer. But this type of cinch should not be "over-cinched" and is not necessarily more comfortable for the average pleasure horse.
Many consider genuine Mohair and Alpaca cinches the best cinches made. Wool and Alpaca fibers help dissipate the heat. Their ability to stretch and compress (known as “crimp”) makes them a superior compression protector to help prevent both pressure and friction. They both have a unique ability to deal with perspiration, wicking the sweat off your horse’s girth and distributing it throughout the cinch material and away from the skin. Wool and Alpaca can absorb and wick up to 3 times their weight in water to keep the area under the cinch dry and comfortable. They can be cinched tight but have a little give for easier breathing and more comfort. Alpaca is a little softer than mohair, which is made from goat's hair.
