RockTape Assassins Knee Sleeves - Pair

Rocktape Assassins Knee Sleeves - 5MM - Pair

Several factors help set Rocktape’s new Assassins apart from many standard knee sleeves on the market. First is quality construction; Assassins are made from a synthetic fabric shell bonded to SBR neoprene (5MM thick) and secured with double-mauser stitching. Second, these sleeves are designed for the high-performance athlete training at the competition level—with extended length for greater stability and tracking of the knee through a wide range of functional athletic movements (including weightlifting, where lateral stability is critical). Third, it’s the graphics—few sleeves have a design that stands out quite like the Assassins. And finally, there’s the value, as all Rocktape sleeves are sold in pairs and packaged with a one-year warranty.

Beneficial for athletes of all sizes and skill levels, Rocktape Assassins effectively compress the vastus medialis (a part of the quad muscle critical to knee extension) just above the patella. This design, combined with heat-sealing seams, ensures optimal comfort, contouring, and blood flow. Wearing a pair of Assassins can result in better performance today and reduced knee pain tomorrow.

Most in-stock orders made through Rogue Fitness before 3pm will ship the same day. You can follow the progress of your order online using the Rogue Shipping Tracker.

*The vastus medialis muscle is one of four quadriceps muscles. It is located on the inner part of the front of the thigh. The lowest part of the vastus medialis, called the vastus medialis oblique (VMO), achieves its maximum contraction during full extension. The VMO helps to stabilize the patella and allow it to track properly.

Rated 3 out of 5 by from Knee sleeves love them except for fit, I followed the measurement guide but they are a little to loose. I ordered elbow sleeves also and they are amazing and the fit is perfect

Rated 4 out of 5 by from Good fit So I have a lot of popping in my knees during squats, I thought these would be the answer to my old age and they are not. With that being said they fit great and do offer support on the way up from a squat

Rated 1 out of 5 by from Too snug I bought these sleeves in the hope they would last longer than the current brand I use. I measured as suggested. They’re so tight it actually cuts off the circulation to my calf . I was hoping they would stretch out but no such luck. I really wanted to love them however not feeling my calves makes it kinda hard. I do not recommend them.

Rated 4 out of 5 by from Helped Me Get Through Spartan Bought these on a recommendation from one of the gym trainers. However, they are too big wish I would have ordered a size smaller. I still get support for my knees and will continue to wear them despite being too large.

Rated 4 out of 5 by from Feels good Overall feels good. I used the sizing chart which indicates that if I was on the high end of a size then I should move up one size. After wearing them I would have preferred to stay at my original size.
