Stick saver hoops are a Slingerland style hoop which has the top edge rolled inward slightly give more of a rounded striking surface, thus prolonging the life of your sticks...
The hoops feel a little beefer, to me, that typical triple flange hoops...
Go back and look at this first pic and you'll notice that the striking edge bends inward, instead of outward...
and no it's not the same as those UGLY S HOOPS I saw at the namm show...lol
