the volers are the best bib ive worn, but ive never spent more than 60 bucks on bibs before, so i dont have much to compare to, but my cat2 teammate says they are great, so ill say they are good.
it might depend on which model voler bib you get though. the suspender bib part soaks up alot of sweat, the chamois is really comfortable, even to walk around in. i wore mine from for about 7 hours saturday before getting on the bike at our teams crit and hardly noticed.
