What each horse gear slot does in The Witcher 3
Roach takes four pieces of Witcher 3 horse gear: a saddle for gallop stamina, blinders for fear resistance, saddlebags for carry weight, and a trophy that adds its own bonus on top. Each piece here lists the exact numbers the game files give it.
Fear is the one that decides whether a chase works. Riding past drowners or a nekker camp panics an unequipped horse and throws Geralt, so blinders matter more than the stamina on a map where you cross open country.
Where the best Witcher 3 horse gear comes from
Most horse gear in The Witcher 3 is bought from stable hands and merchants rather than found, and the best pieces sit with traders in Novigrad and Toussaint. The merchants page lists who carries what.
Monster trophies use the same slot logic and are covered on the Witcher 3 trophies page, where each one lists the bonus it gives while strapped to the saddle.
