Rehband Rx Knee Sleeve - 3mm - Black

Rehband’s Rx Knee Sleeve is a great option for light support with maximum range of motion. Made from a 3mm thick SBR/Neoprene blend, the Rx support is 2mm thinner than the Rehband 7751 series, and offers a useful intermediate level of compression—particularly for athletes with motion-heavy, high-intensity training regimens.

This version of the Rx Knee Sleeve is black. Each sleeve is sold individually and available in sizes XS to XXL (see the Rehband sizing chart below). Whether you’re looking to reduce the risk of a knee injury or are rehabbing from a previous setback, these simple, durable supports can make a noticeable difference.


  • Sold Individually

Rehband Rx 3mm Knee Sleeve is rated 4.5 out of 5 by 27.
Rated 5 out of 5 by from Can't go wrong Can't go wrong with these knee sleeves. I've tried all different types of knee sleeves and Rehband by far is the most comfortable, has great support, and amazing quality. Great for everyday use on light workouts, but would not recommend them for heavy lifting.

Rated 5 out of 5 by from 3mm great for extended time wearing I bought a pair of 7mm but they were too stiff to wear for lengthy sessions. Usually squat in them then pull em down. The 3mm are perfect for 1-2 hours at a time. I wear the 3mm all afternoon while training clients

Rated 5 out of 5 by from Awesome Product! I bought this about a month ago. I bought 2 so that I had one for each knee. It helps to make me feel more stable in my squats, cleans, snatches, thrusters, etc. I would recommend this for sure.

Rated 5 out of 5 by from Great product. Take the time to measure. I ordered small, had to return for a medium. Had to pay shipping cost. Measure twice order once.

Rated 5 out of 5 by from Glad I purchased! I’m really happy with the fit of these. The size chart was spot on. I use them during crossfit wods and squatting heavy. Nice support without being too restrictive.

Rated 5 out of 5 by from They Feel Great! I'm happy that I bought these. I haven't used them in the gym yet, but have used them snowshoeing and cross-country skiing. They kept my knees warm and stabilized (since one of my knees is an implant, this was key to performance). I wish I had known about them long before now.

Rated 4 out of 5 by from Tough I bought the pair of knee sleeves a few months ago. Both of the sleeves are very well made. I followed the size chart but the top of the sleeve keeps sliding down, so next time I buy some I’ll buy one size smaller. I went with the xl. Over all the product does its job.
