Does anyone know if the Circle Y Equitation saddle comes in a 17 or 18" seat? Trying to find a saddle for my husband and this is the style he likes but I cannot for the life of me find one bigger than a 16. So I thought I would check and see if my quest is pointless! Or if someone knows of a saddle that is similar in style but comes in a bigger seat, I'd like to know about that too! Thank you so much for your time and any info you can give me!!
