Are you looking for Cotton reins? Cotton reins are generally not manufactured by tack companies because cotton fiber reins are likely to stretch or break when under pressure. We sell a type of cotton covered rein that is just as soft as cotton reins but much more durable and slightly thinner, to fit better in the hand. These reins have a braided cotton cover surrounding a poly-pro core. This means the reins are static and will not stretch, yet they are just as soft as cotton. The more often you use these cotton covered reins, the softer the reins get. They may be used for Western gaming, trail riding, or schooling English or Western riding. They are constructed in one piece so you cannot drop your reins. These are excellent for small children or riders who like a rein with a soft touch.
