Mammal Strength Stiff Knee Sleeves PRO are built for maximum joint stability, compression, and support under extreme loads, delivering competition-level performance and rebound for powerlifting, strongman, and heavy strength training.

Key Benefits:
Ultra-stiff neoprene construction delivers maximum knee support under heavy loads. High-compression fit helps stabilise the knee joint during squats and maximal lifts. Designed to provide rebound and confidence out of the bottom position. Maintains joint warmth and rigidity throughout heavy sessions. Built for durability and repeated high-intensity training.

Who For:
Powerlifters, strongman athletes, and advanced strength athletes lifting at high percentages. Ideal for those who prioritise maximum support and stability over mobility. Best suited for heavy squats, max-effort lifts, and competition-style training.

How To Use - KEY STEPS:

1. Fold the cuffs & roll them down to at least 1/3 folded
2. Pull them up past the knee joint and then roll the folded section above the knee joint 
3. Position so the sleeve sits evenly above and below the kneecap
4. Use during heavy squats and maximal lower-body lifts
5. Remove after training to allow circulation to return
