Sam is 1/2 curly horse, but you can't really tell in the summer. Not so in the winter. While he doesn't get ringlets in his mane and tail, or curly-cues that make his coat look like a poodle, he does grow a pretty awesome soft, crushed velvet pattern.
He does wear at least a rain sheet this time of year and it's a 'wug' that goes up his neck a bit. You can kinda see right where it ends, defining the thicker section of his upper neck.
