Bucas Buzz Off Full Neck Flying rug Gr.155 brand new

Bucas Buzz Off Full Neck Flying rug Gr.155 brand new - I sell a brand new (only to try on the horse lain) Bucas fly rug. Unfortunately, it has become too tight on my horse's chest over the winter.
I bought the blanket last year in the fall to be well equipped in the spring of 2023. But my horse has changed physically over the winter so that the blanket now no longer fits.
