OSO Barbell Collars
$55 & FREE Shipping
OSO Barbell Collars are quickly becoming the collar of choice for many competitive weightlifting and functional fitness athletes.
A pair of Fringe Sport branded aluminum barbell collars are made with 6061 billet aircraft grade aluminum (they're made to take a beating) and their revolutionary design makes them almost impossible to slip on the collar.
We are very proud of all the different collars we carry and while each have their purpose, these are by far the finest collars we have come across yet.
