I've decided that I eventually want to get Jetta a breastplate because I don't have one and while jumping the saddle slips back slightly. Also, literally everyone has one in eventing so we have to fit in, right? ;) Anyways, I'm torn between a regular 3-point breastplate and a 5-point breastplate. My two favorites are the Antares Leather Breastplate and the Voltaire Convertible Breastplate.
What I like about Antares is that it is very well made and gorgeous. It is has a padded wither strap and an elastic insert.
