I have one pair of Performance Ultra shorts, and pair of Ultra bibs, a pair of voler Hammer Nutrition bibs and a pair of Hammer Nutrition shorts. I personally MUCH prefer the voler bibs/shorts to their Performance counterparts. The chamois is very comfortable, the cut is much more aesthetically pleasing and the legs are substantially shorter. The big problem I have with the Ultras is that the damn legs are so long the hem practically touches my kneecaps, and I don't have short legs.
