Super Training Extreme "X" Knee Sleeves

From the makers of the Sling Shot brand, the newly redesigned Extreme “X” Knee Sleeves are built for absolute maximum support and minimal stretch. Already the stiffest compression knee sleeves in the Sling Shot line-up, and arguably the stiffest in the industry, this updated design is now approved (as of 2019) by the USPA and IPF, and no longer includes the non-slip grip tech of the original model.

Extreme X Sleeves are sold in pairs and available in seven size options from Small to 4XL. The 7mm thick, Level 4 neoprene construction and stiff front panel offer enough support for max effort lifts, and the sleeves won’t bunch or slide as you train.

Comparison: Tighter fit than STrong Knee Sleeves, thicker than Grippy X Sleeves.

Super Training Extreme "X" Knee Sleeves is rated 4.4 out of 5 by 12.
Rated 5 out of 5 by from Very tight and doesn't move I have had several surgeries on my knee and a bit of arthritis and as soon as I put these on the difference I felt was incredible my confidence with my squat went up dramatically. I was able to perform squats with a better range of movement and no pain and able to push with both legs again and the tightness supports knee very well and keeps swelling allowing faster recovery in-between gym days and they do not move during your set. Make sure to take the time to measure your fit correctly as suggested by Rouge website. I have not tested them over a long period of time so I don't know how much they stretch over a long period of time.

Rated 5 out of 5 by from Indestructible These knee sleeves are great quality and will do the job of supporting the knee joint. Be careful with sizing: if you are on the uppermost end of one size you might want to size up. These knee sleeves aren’t as elastic as some, so getting them on is hard. Mark Bell has a video on YouTube, “How to put on knee sleeves.” Might sound easy, but there is a technique. Fold them in half by turning them inside out, slip them over the calf, then pull them up over the knee. These sleeves are also longer than most, so you can’t just pull them on.

Rated 5 out of 5 by from Tight Fit!! The third set worked. Had to return the first one and kept the second while I'm currently using the third. They should really address the measuring. Completely inaccurate. I would recommend ordering two sizes up. The first would not fit beyond my calf. The second would just barely go over the knee (good for dead lifts) after a good pull. The third fit as it was advertised - tight, but works very well which is why I gave it a five. Second day I wore them I squatted another personal best.

Rated 5 out of 5 by from Serious sleeves! These are the best sleeves I have ever used or owned. I bought a pair two weeks before a meet I had trained 8 months for and they instantly felt comfortable and supportive. My best meet squat went from a previous 440 to 485 pounds. I had also never squatted more than 475 in training. I look forward to spending more time training in these sleeves and wringing out even more poundage.

Rated 5 out of 5 by from Stiff but run snug I have probably 20+ sessions with these under my belt. They are quite nice. The material is stiff and when they say if you are between sizes to go one higher they are accurate. Don't expect them to expand much as you use them. But the support is good. They stay in place better than others I have used. If you need more support get knee wraps.

Rated 5 out of 5 by from Game changers! These are worth the money. I have been a competitive powerlifter for nearly ten years now and these are the best knee sleeves that I’ve ever had. They do fit snug for sure. Ordering one size up might be a good idea.

Rated 3 out of 5 by from Not as durable as SBD After just a few sessions they get loose, it’s easier to put them on but they feel like my 6 years old SBDs (same size) after 3 weeks. Still good to go but I dunno how they will hold out in the future.

Rated 5 out of 5 by from Durable Love this product!!! I had a major knee surgery about a year and a half ago and these sleeves keep everything tight and helps reduce the strain on my joints.
