OSO Barbell was a company born out of a need. Born out of a frustration for the alternative. Who hasn’t either had weights move during a heavy lifting day or struggled to get those spring collars on/off quickly when seconds count. OSO Barbell set out to make a better collar, and that is just what we did.
The OSO Barbell collars, conceived by Industrial Design Engineers, with input from all over the Crossfit world, were only meant to be functional. However, the finished product was something quite different. Not only will theses collars keep weights in place, but they will look good while doing it.
OSO Barbell is committed to making quality products here in the USA.
