I can find bands like this for $12 else where but these are much better. The length, the clip, the loop grip/cuff are all worth the price.
My son is a very tall and strong 12 year old so we bought the adult size. It's great but I may buy the youth bands too. The greater resistance of the thicker adult size is better for 60% of the exercises but some of the finer movements that isolate the different directions for rotator cuff work could be better served by the lighter youth bands.
