using Thorowgood's interchangeable SimaTree gullet bars, allowing the saddle to accommodate changes in the horse's condition or potentially be fitted to different horses. The Original GP uses the R-Bar system, with widths available from Narrow/Medium through Extra Wide/Extra Extra Wide.
 
The saddle features broad, 100% British wool-flocked panels, allowing a qualified saddle fitter to make adjustments to the flocking for a more individualized fit. Its open-headed tree and broad panel design are intended to accommodate a range of standard horse conformations.
 
The T8 also incorporates adjustable knee and calf blocks, allowing the rider to customize leg support and position. Multiple girthing options, including point and balance configurations, provide additional options for improving saddle stability on the horse.
 
The moderately forward all-purpose flap provides enough room for a shorter stirrup when jumping while remaining appropriate for everyday flatwork and trail riding..

A particularly practical saddle for riders who value fit adjustability. The combination of an interchangeable gullet and wool-flocked panels gives a qualified saddle fitter considerably more scope for adjusting the saddle than a fixed-tree, foam-panel saddle.
