I love my Saddle Pocket. It’s incredibly handy, carries everything I need, and never needs to be cleaned or conditioned. You can read my full review on Tack Guru.
Just be forewarned. If you have more than one saddle, you will probably need more than one pocket. Once you get used to having one, you will miss it. If you buy them when they are on Tack of the Day, they are a real bargain!
