If you can afford it, then something like an ESP or a 5 Star pad would be a good choice, but if you're on a budget like most horse people
, then Diamond is a great company to go with. Most of the working cowboys I know (guys who put 8+ hours a day of hard
labor on their horses) use Diamond felt pads because they are great quality and don't take a week's wages to replace when they wear out....and all pads wear out if you ride enough.
Most typical cheap pads are 1" thickness and so is this 1" Diamond Wool Contoured Tough Saddle Pad
But if you don't need that thick of a pad, then they also have a thinner one, but it's more expensive because it's made of different wool. Diamond Wool 1/2" Contoured Cowboy Pad
They've also got one that's 3/4 inch if that would fit better.
