The PRO is our stiffest, most supportive sleeve, built for maximal loads. It also needs the most care when it comes to sizing. Here is everything you need to know.
What They Are
The Stiff Knee Sleeves PRO use ultra-stiff neoprene in a high-compression fit for maximum knee stability, rigidity and rebound out of the bottom of a squat. They are built for heavy, repeated, high-intensity training.
Who They Are For
- Powerlifters and strongman athletes
- Advanced lifters training at high percentages
- Anyone who puts maximum support and stability ahead of mobility
Who Should Look Elsewhere
- Olympic lifting or CrossFit? The PRO's stiffness works against fast, deep positions. Try the V3 7mm or V3 5mm.
- Want something you wind on for single heavy sets? See Knee Sleeves vs Knee Wraps.

How to Get Them On
- Fold the cuffs and roll them down so at least a third is folded over.
- Pull the sleeve up past the knee joint.
- Roll the folded section back up above the knee so the sleeve sits evenly above and below the kneecap.
How to Size Them
The PRO is measured differently from our other sleeves, and accuracy matters more because there is minimal give.
- Knee (decides your size): 10cm below the centre of the kneecap
- Quad: 10cm above the centre of the kneecap
- Calf: the widest point below the knee
- Sizes: S, M, L and XL
Measure close to exact. Do not round up or down.
Looking After Them
Remove them after training to let circulation return to normal, hand wash cold and air dry away from direct heat.
