How to Choose 7mm Knee Sleeves
Why 7mm?
5mm sleeves are lighter and better for running and CrossFit. 7mm sleeves are stiffer and warmer, which suits heavy squats.
Sizing
Measure around the knee or calf as the brand instructs. A snug fit is normal; a fit that cuts off circulation is too small.
Competition approval
If you compete in powerlifting, check that your federation approves the sleeve, such as the IPF-approved Gymreapers pair.
Pair vs single
Some premium sleeves are sold one at a time. Check the listing so you do not end up with one sleeve.
FAQ
Are 7mm knee sleeves good for squats?
Yes. They are the most common choice for squats because they add warmth, compression and a small rebound.
Should knee sleeves be tight?
They should feel snug and firm but not painful or numbing.
Can I run in 7mm knee sleeves?
You can, but 5mm sleeves are usually more comfortable for running and jumping.
How do I wash knee sleeves?
Hand wash in cool water with mild soap and air dry. Avoid the dryer, which can damage neoprene.
Final Verdict
Iron Bull’s 7mm sleeves are the best choice for most lifters thanks to strong compression and thousands of positive ratings. Competitors should choose the IPF-approved Gymreapers pair, and budget shoppers can start with Jupiter.
