NEW from RockTape, the ultimate weapon for workout domination - Assassins, an entirely new generation of knee sleeves. Assassins will keep you ahead of the game--keeping your knees supported and protected while slaying reps and crushing WODs.

  • Provide joint support during grueling workouts and lifts
  • Protect the knee from abrasions during lunges or obstacle course racing
  • Provide VMO (vastus medialis oblique) support 
  • Stay put with a unique organic design, won’t slip down during activity
  • Keep the knee joint warm between exercises
  • May help reduce non-specific knee pain* 
  • May help improve patella tracking over the knee cap

Assassins can be used in a variety of sports and fitness pursuits, including: weightlifting, high-intensity interval training, obstacle course racing, running, cycling and other functional fitness endeavors.

Assassins are available in sizes extra small through extra large, with two thickness options: 5mm for moderate support and 7mm for maximum support.

Built for Competition

Assassins were formulated with the unique needs of athletes in mind, and unlike sleeves from other companies, are much more than a re-purposed medical knee support.

We fine-tuned Assassins through three years of feedback from both RockTape customers and professional athletes Ashley Horner, Marcus Filly, and Neal Maddox to provide the ultimate knee supports.

The result is a pair of knee sleeves that are suitable for the most grueling workouts, lifting events, and obstacle course races - yet comfortable enough for the weekend warrior.

Designed for Performance

Taller than standard sleeves, and carefully constructed with a unique organic design, Assassins support the knee and compresse the vastus medals oblique (VMO) at its insertion point above the patella. This helps ensure proper stability and tracking of the knee, and can often dramatically reduce non-specific knee pain*, particularly during squats.

The extra-tall design also keeps sleeves in place - preventing excess slippage and shifting during workouts - a common complaint of competing sleeves.

Uncompromising Value

Protective gear should always be reasonably priced and available to anyone. We also believe that every athlete deserves two sleeves - that's why Assassins are always sold as a pair.

When compared to the competition, Assassins' quality and price can't be matched.

Nearly Indestructible

Engineered with a synthetic fabric shell bonded to SBR neoprene and secured via double-mauser stitching, Assassins comfortably support the knee joint through countless workouts.

Rigorous life-cycle testing by both our own athletes and automated test programs guarantee superior quality. If any pair of Assassins fails to carry out their purpose, RockTape offers the industry’s only one-year warranty against defects and premature failure from date of purchase.

Measure the circumference of your knee around the center of your patella.
Assassins start very snug and can take a few sessions to break in.
If you measure on the higher end of a size, we recommend ordering the next size up.

XS: 10.5" and below
SM: 10.5 - 12.5"
MD: 12.5 - 13.5"
LG: 13.5 - 14.5"

These are by far the best knee sleeves I have ever used. I crossfit 4-5 times a week, Lots of squats and they have lasted longer than any of the other 5 brands I have used, even longer than Rehband!

Great sleeves at a great price

Pretty good sleeves glad I found these before I spent almost $100 on a pair

Pretty good

Written by Matt on 20th Nov 2017

Sleeves have been one of the best investments I made for CrossFit. They fit nicely, generally don't slide down during a Wod, provide moderate support, and keep the knees warm and protected. However, the neoprene in the sleeves started to tear at the top of the sleeve after a couple weeks of use. I waited a while then cashed in on RockTape's excellent warranty program but the same thing happened again. So if you have big quads, they may not last as long as you'd like but other than that, they have been phenomenal.

The best

The best knee sleeves got the 5mm large red camo, I couldn't be happier with the warmth and support of these.

Great Knee Sleeves

Written by Christy A on 27th Feb 2017

I was hesitant to purchase these, thinking that maybe there was a equivalent brand somewhere out there, but I am not disappointed. I can feel the support compared to my old sleeves and they don't roll! It makes a huge difference lifting, and even running for me.

I purchased a pair that felt amazing and performed better than I expected. They didnt roll, pinch or slide. After 4 or 5 workouts I developed some seperation and fraying at the top of one sleeve and customer service replaced them in 3 days. 3 days at my door!!! Great product and highly recommend.

Better than the previous version

Written by Annie on 2nd Oct 2016

Great compression, warmth and stability. They aren't supposed to roll like the previous versions, and they don't, but they do bunch up with multiple reps.
