About this product
These are Rogue Fitness OSO Barbell Collars, a set of 6 collars made from aircraft-grade aluminum. Designed for weight training and dumbbell use, they clamp securely to barbells or dumbbells to keep plates in place. The OSO model is well-known in the fitness community for its reliable locking mechanism. This pack includes six collars, providing plenty for multiple bars or sharing in a gym setting.
Our take
I snagged these Rogue OSO collars hoping for a secure hold, and they deliver. The aircraft-grade aluminum feels premium and lightweight. They slide on easily and lock tight—no slipping during dynamic lifts. Having six in the pack is a bonus for a home gym with multiple bars. My only gripe is the price; $75 feels steep for collars, even quality ones. Also, they're a bit small for thicker bars. But for standard barbells and dumbbells, they're fantastic. Solid buy if you value security and don't mind the cost.
