Cavallin Mini / Midi

Here's a perfect saddle for youngsters! The Ghost Mini has the Cavallin base and integrated pad of the Bareback Pad models (Mandriana, Toscana, etc) but a seat styled after the standard Ghost models. And it's 30cm (12") from pommel to cantle - compared to 15" for the same measurement on the bambini (16") models, so 3" smaller! Adjustable range ~12-13".
The Midi is a slightly larger version of the Mini, also on the Cavallin BBP base and in between the Mini and a Bambini for size at 2" bigger along the spine but otherwise dimensions are the same. Adjustable range 14-15".
The stirrup hanger is velcro so can be adjusted as your child grows.
For an even smaller, super secure saddle for toddlers, check out the Buttera Vittorio.
