Flex2® saddles are designed to include comfort features for both the horse and rider that work in synergy with the Flex2® tree. Only Circle Y has the exclusive Flex2® tree design which uses a rigid ground seat for rider support, a high density bar which disperses rider weight, and low density bar which is against the horse and provides give for freedom of movement. This results in a lightweight saddle that’s an option for riders of all sizes and is proven to fit a wide variety of horses or mules. The Flex2® tree will never get wider over time, flex in half, or overflex to create pressure points if properly fitted. Give yourself and your horse the lightweight comfort you’ve been craving!
