Rehband Rx Knee Sleeve - 7mm - Black

Rehband's 7mm Rx Knee Sleeve is designed for an extra level of support for heavier lifts or focused rehabilitation training. A full 40% thicker than the standard Rx 7751 Knee Supports, these heavy-duty SBR/Neoprene sleeves deliver maximum joint compression to promote better blood flow and reduce the direct strain on the knees during squats, Oly lifts, and Strongman workouts. Whether you're battling back from nagging knee injuries or looking to prevent one, a thicker knee sleeve can provide some much needed peace of mind.

This version of the 7mm Rx Knee Support is black. Use the sizing chart below to determine which measurement of the sleeve is best for you. If you’re looking for a tighter, competition fit, consider selecting a sleeve one size smaller than the chart suggests.

Rehband Rx 7mm Knee Sleeve is rated 4.7 out of 5 by 51.
Rated 5 out of 5 by from 2mm does make a difference I've been wearing 5mm knee sleeves and still getting some niggling pain that would come and go during lifting sessions. I weigh in at 235lbs and almost 40 so I'm not a light weight, young Crossfitter and the knees have had a hard life after many years of parachuting. The 5mm felt ok but after trying the 7mm for a couple of weeks I couldn't be happier. You can feel the difference even as you are trying to put them on. They are noticeably thicker but they haven't effected my mobility or range of movement at all and most importantly it seems to have stopped the knee pain. Of course I should probably fix my knees but that's a different issue... I highly recommend the 7mm knee sleeves.

Rated 5 out of 5 by from They fit perfect ! I have torn cartilage in one of my knees and was struggling to go my workouts. So before jumping into surgery I decided to try the sleeve. I am super happy I did !!! No pain at all at this time and I’m back hard at it .....

Rated 5 out of 5 by from true to size, gives a lot of stability I have an existing knee problem that I haven't addressed to the doctor and the pain would come and go. I purchased this to see if it can help ease the pain during squats and I'm glad to say that it did. After 150 wall balls my knee didn't feel like it had been whacked multiple times with a hammer. Whether you have knee problems or not, these must be in your life.

Rated 5 out of 5 by from Awesome Sleeves Used these today for a workout that would normally leave my knees a bit sore, consisting of rowing, burpees, and snatch. No soreness with these. Also felt very stable and secure with these on. I measured on the low end of medium, and went with the small; they fit perfect.

Rated 4 out of 5 by from It worked for me I a 65 soon to be 66. I played basketball most of my life. I love the game and have failed to eliminate active participation from my life. I have had knee issues to include surgery. My knee feels better when it is warm, this sleeve captures my body heat quite well. My knee feels loose and the sleeve provides me with enough support to get back on the court again. 7 mm was the perfect choice for me.

Rated 5 out of 5 by from Best knee sleeves on the market!! I've tried several different brands and type of knee sleeves, but the Rehband Rex's are by far the best. They don't slip, even after much wear and tear, are easy to clean, and provide the support and warmth I need, for my old knees.

Rated 5 out of 5 by from Saved my knees!! I bought these because I was starting to have problems with my knees. All I can say is these were a life saver. I am now able to do squats like I use to do them when I was younger. A little pricey but worth it. Best investment ever!

Rated 5 out of 5 by from Worth Every Penny I've been using these knee sleeves for a month, and there's no way I'd lift without them. I don't have knee problems, but as I've increased the weight I'm lifting, I'm finding knee stability is a thing--but not with these sleeves. They keep your knees warm and stable. My measurements were at the top end of the medium range, and I'm glad I chose the medium and didn't go up to the large. As the sleeves warm while you wear them, you do get a little stretch, and the large would have been too big.
