During development, Buckingham looked at feedback around the industry including proper fit, adjustment slippage, mobility of suspension systems, proper support at legs and back, lower hardware options and other attachment options throughout the suspension, and a plethora of other issues with saddles around the industry. The handmade in the USA Agility saddle was designed and built for "Work" with a focus on comfort, durability, mobility, and functionality.
