OSO Mighty Collars
Multi Color

Designed and manufactured in Colorado using aircraft-grade aluminum, OSO Mighty Collars offer many of the same benefits of the standard OSO Barbell Collar in an economically priced model.

These super lightweight collars—available here in Gun metal and Blue—are sold in pairs and equipped with a rubberized interior lining to protect the bar. OSO Mighty Collars deliver a secure, stable hold through repeated, high-impact drops, and allow easy adjustments or removal with a simple lever and lock/unlock mechanism.

OSO Mighty Collars is rated 4.4 out of 5 by 36.
Rated 5 out of 5 by from Great price, better quality Easy to put on and take off, plates don’t budge during lifts or wods

Rated 4 out of 5 by from Great clips for a great price! I bought these for Crossfit since we're constantly dropping/slamming the bar or doing lots of other dynamic movements and the standard bar clips have a tendency to slide off. The OSO clips have been great so far! I love the low profile design, they're very lightweight, sturdy construction, and once they're locked they won't budge. The only downside, and the reason i gave them a 4 star rating, is that they can be cumbersome to slide on. They only open up to be JUST larger than the bar and tend to get stuck as you put them on. If the workout only requires one weight then it's no big deal, but if you're using multiple weights or have to switch weights during the workout it can be very frustrating. Otherwise, great product!

Rated 5 out of 5 by from Love these I bought them about a month ago. Love them due to the fact that you don’t have to fight with the spring clips. Keep plates in place.

Rated 4 out of 5 by from Functional but fiddly. It works well enough but it has a rubber liner and that grabs the bar a bit while you're putting it on and taking it off.

Rated 5 out of 5 by from Great for the price I started working out my 12 year old son and he struggled with the spring collars. The OSO collars are quick and easy.

Rated 2 out of 5 by from Wish I bought a different set These are too thin, hard to clip and unfortunately not something I can recommend. I bought a rack, weights and benches from Rogue, but wish I ordered a different set of clips. In fact, after 2 weeks of use I am so annoyed with these that I just ordered a different set of clips. Hopefully they will be better.

Rated 3 out of 5 by from It’s a budget collar I feel bad giving this too harsh of a review because this collar is meant to be a budget item, but even still it fell short of expectations. Its diameter is just barely bigger than an Oly bar, so it’s a pain to get on and off, and often sticks/catches. The lever is also too tight and feels brittle at the same time. Go for the more expensive OSO collars, you'll be glad you did.

Rated 3 out of 5 by from Not quite sure yet I have used these a handful of times and I am still not sure if I like them. Just not quick enough when you have to change the weight several times in a WOD. They do keep the weight stable and do lock in well so I have them 3 stars.
