I think describing the exact brand names is a little excessive and also I would not use shipping boots, I'd wrap their legs for trailering but other than that yes, it's pretty standard. It also seems to include some schooling tack as well that you probably already have. If it gets super expensive, try buying some things cheaper. Instead of a Charles Owen helmet, get an IRH. They're perfectly acceptable for 'A' shows and they're a lot cheaper. And 'Grand Prix' sells some nice breeches that are cheaper than the Tailords.
The essential joy of being with horses is that it brings us in contact with the rare elements of grace, beauty, spirit, and fire. ~Sharon Ralls Lemon
