Not sure if this is what you are looking for, but I ran across this vest at the below site. They have a F.O.S. (Friday only sale) each Friday and this vest (Doggy Doggles Biker Gear) is on sale. Keep scrolling and you'll run across it. Take a look! They may not have it in the size you want. They sell out quickly. I think I'm going to be addicted to this site!
