This is my second pair of knee sleeves. I bought the 5 mm in xl and have found them to fit nicely, giving me support and helping me with some annoying pain I’ve been having. They don’t aggravate me when running sprints during a WOD, and give great support for most other movements and weight lifting. It is recommended to get the 7mm for olympic lifting. Since most of my workouts are CrossFit style high intensity, the 5 mm are sufficient. The sleeves give me more support than my previous pair and have helped me hit some goals. I highly recommend them. Rock Tape knows what they’re doing!
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 forearm support during lifts, rows, and more
- 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.
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.
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.

Great knees sleeves they keep everything warm and help prevent injuries. They are also great for protecting your shins during rope climb and box jumps.
I've never used knee sleeves before because I always thought it was silly to buy them one at a time, so when I heard about RockTape's offering, I figured it was time to finally give it a shot. I like them. They protect my knees from scrapes and rocks when doing lunges in my driveway, and from rubber burn when doing burpees in the gym. When I'm running or squatting, I feel like there are springs in my knees now -- the support from even the 5mm ones is incredible. Do yourself a favor -- if you were on the fence, get down and buy a set, you won't regret it.
I ordered a pair of knee sleeves in size M but after trying them on I realized I needed a Large. They exchanged them without question and got the right pair to me very quickly. I love these sleeves - they feel snug and secure and help my knees feel stable throughout workouts.
