If you live in a climate where winter provides more active riding days, where faster work or jumping might be possible, choose this clipping option. Start as per the low trace clip, but swing the line back from a much higher point—from midway down his shoulder, back to a line that ends about half-way down his hindquarters. (The line will hit a level that’s about even with the bottom of your saddle flap.)
A horse should not live outside with this much hair removed unless he’s in a temperate region and even then he’ll need blanketing. This clip will probably require one medium stable rug, one medium turnout and a stable sheet or lighter blanket to layer under both in extreme cold.
