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.

Use the Fit Guide below to determine the correct size sleeve for you.

Super Training Extreme "X" Knee Sleeves is rated 4.2 out of 5 by 13.
Rated 2 out of 5 by from Too small I followed the sizing guidelines and even adding a size up as per the recommendations. They still don’t fit!

Rated 4 out of 5 by from Good while it lasted Had these less than 3months before the fabric tore... was good while it lasted

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 New to training sleeves I have a terrible knee as well as week hip adductors. These make me feel stable in the hole when I am squatting heavy

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 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 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.
Date published: 2019-08-30
Rated 4 out of 5 by from Good for heavy lifting I have used these now for squatting and dead lifting and so far so good for support and padding on the heavy lifts.
