It isn't a hard and fast rule, of course, as the examples that Iride and Always mentioned are obviously in top condition, but I have experienced it to be relatively
true that a horse who is used to sweating takes more to leather than a horse who isn't used to sweating. I read that it's something to do with dirty buildup in the pores contributing to lather, and sweating clears those dirty pores out.
Friction is just going to make lather no matter what; reins against the neck, breastcollar against the chest, or between the hind legs. Mixing air in makes froth in sweat, no matter how great of condition the horse is in.
